The drawback to Einstein’s Special Theory of Relativity, however, is that it is “special” in the respect that it only considers the effects of relativity to an observer moving at constant speed. At around this time (1907), he also started to wonder how Newtonian gravitation would have to be modified to fit in with special relativity, and how the effects of gravity could be incorporated into the formulation. Initially, Einstein had been puzzled by the fact that Sir Isaac Newton’s Law of Universal Gravitation, which had stood undisputed since 1687, appeared to be fundamentally incompatible with his own Special Theory. Thus, according to this theory, gravity is relatively strong when objects are near each other, but weakens with distance, and the bigger the bodies, the more their force of mutual attraction.
Gravity is the organizing force for the cosmos, crucial in allowing structure to unfold from an almost featureless Big Bang origin.
Even before Newton, the great 17th Century Italian physicist Galileo Galilei had shown that all bodies fall at the same rate, any perceived differences in practice being caused by differences in air resistance and drag. Newton, however, had assumed that the force of gravity acts instantaneously, and Einstein had already shown that nothing can travel at infinite speed, not even gravity, being limited by the de facto universal speed limit of the speed of light.
Einstein’s ground-breaking realization (which he called “the happiest thought of my life”) was that gravity is in reality not a force at all, but is indistinguishable from, and in fact the same thing as, acceleration, an idea he called the “principle of equivalence”. The influence of gravity also creates effects of time dilation (see the section on the Special Theory of Relativity for a more detailed discussion of time dilation), sometimes referred to as "gravitational time dilation".
On a much smaller scale, because gravity is slightly stronger closer to the centre of the Earth, then theoretically time passes more slowly for someone living on the first floor of an apartment block than for someone living at the top. So, gravity, Einstein realized, is not really a force at all, but just the result of our surroundings accelerating relative to us.
Derive an expression for gravitational field strength at the surface of a planet, assuming that all its mass is concentrated at its centre. The force between the positive charge of protons and negative charge of electrons is called electric force.
Why don't the oppositely charged protons in the nucleus or electrons surrounding them repel each other and fly apart. There is one underlying principle there that you have met before in a slightly different context. Draw a diagram to show why someones weight on top of Everest is significantly less than at the surface of the Earth.
A physical field is an area in which a force occurs, a gravitational field is therefore a region of space in which an object with mass experiences a gravitational force. When we represent fields, we draw field lines to show the direction of the force acting on a test object. Any two point masses are attracted to each other with a force that is proportional to each of their masses and inversely proportional to the square of the distance between them.
Point masses means that we forget about an object having a size, and consider only its mass acting at a single point (we have come across this idea before, when we considered centre of mass). The inverse square law - this occurs quite a lot physics and is worth going into in more detail. Thus Newton's law of gravitation implies that the gravitational force falls off according to the inverse square law. Then we introduce the constant of proportionality, the universal gravitational constant, G.
If the mass of the earth is 6.0x1024kg and its radius is 6400km work out the gravitational force on a 1kg mass on its surface.
Gravitational field strength at a point in a gravitational field is the force exerted on a unit mass at that point. Read the details of Cavendish's experiment to weigh the Earth, and then complete the worksheet.
An electric field is a region of space in which an object with charge experiences an electric force.
Observe the electric field pattern set up between two charged parallel plates using the polar particles of semolena. The force acting between two point charges is directly proportional to each of their charges and inversely proportional to the square of the distance between them.
Given a physical significance it would denote the ease with which electric field permeates through space. Electric field strength at a point in an electric field is the force exerted on a unit charge at that point. Observe the movement of a test charge movement in different electric fields, with this applet . Have a go at the simulation of Millikan's Oil Drop experiment to determine the fundamental quantity of charge. Basically all the atoms in the magnet are aligned so the electrons are all orbiting the same way. With this in mind and knowing that the earth is spinning we can determine the earth's magnetic field, and see that it looks very like that of a simple bar magnet. Explain why what we call the north pole of the earth is in fact a magnetic south pole (think about what a navigation compass actually is).What force acts on a current carrying conductor in a magnetic field?
This equation work well provided that the direction of the current and that of the magnetic field are perpendicular. We can predict the direction and calculate the force acting on a current carrying conductor placed in a magnetic field. This means with some simple manipulation we should also be able to predict the direction and size of forces acting on moving charges in a magnetic field. An important note: When we were using the Fleming's left hand rule to predict the direction of forces, etc, we were considering conventional current.

If there are two particles m1 and m2 from r distance, then there exists attractive force between these particles named asgiven digram directed from one body to other body and equal to magnitude directly proportional to product of masses of the bodies and inverse proportional to square distance between bodies. To find this we consider a small element of width dx on the rod as shown in figure at a distance x from the point mass in. Still running from the [Stillborn Corrupted Moth “Monarch”], amongst the laser beams and shattering stones, and with Victoria clutching to Athena’s arm like a cute little monkey, the two girls discussed strategy… kind of.
The world disagreed with the mad Princess’ sudden will to turn this fight into a music-hall, and the stalagmite materialised said disagreement with uncaring violence. Slowly peeling away from the stalagmite after her glorious horizontal faceplant, Victoria hurriedly grabbed the uneven stone with her valid hand. In her opinion, that was a very valide way to test the gravity inside Untold Tales, by comparing the acceleration with her mass et cetera… Elric had actually been quite close to determining the exact mass of the planet, but the uncertainty that remained, about the potential passive effect of ambient magic on physics, kept bothering him. Ultimately though, she decided against committing educated suicide – for the sake of the team.
Sensitive to the creature’s newfound sense of self, Victoria actively went back to sending Monarch its first birthday candle. Right before her pitiable strength failed to continue supporting her own weight, Victoria casted the spell. A small crack, barely a couple decimetres deep, spread from the edge she had been clinging onto.
As soon as the now familiar darkness – Victoria became familiar easily when something interested her – receded, the dhampir girl found herself safely on the ground and witnessed her soulmate crashing along with the stone tusk. Actually, because it was Athena, and because she was both calculative AND badass, she hadn’t just “crashed” with the stalagmite.
With all the debatable might of her untrained pins, the feeble and frail girl tentatively limped forwards with less velocity than an arthritic sloth under morphine.
Trying to ignore the annoying divinity, Victoria stood back up and resumed her moderately-paced race towards the cloud of dust, which had been raised by the crashing stalagmite. Rolling her eyes around in annoyance, Victoria accelerated the best she could and, while running, ripped her wrist opened with her teeth. With her [Hematokinesis (Higher)] she controlled her blood, making it flow out of the wound and forming a drill-shaped weapon around her right forearm.


She eventually stepped into a clearing in the middle of the particle haze, where the trashing of the agonising monster had blasted away the grinded stone in suspension. Confronted with such a spectacle, Victoria didn’t hesitate… She took another screenshot… Then she darted for the maw, raising her blood weapon which began to spin even faster, and let her inner fanboy take over her body.
Indeed, Athena was staring with horror at the pointy spinning stake that had just appeared between her legs, from the inside of the monster. From the lance running through Monarch’s brain, innumerable spikes branched out, reducing its nervous centre to shreds. From above the slumping boss, Athena witnessed her friend collapsing on the ground, covered in sticky undead blood and grinning broadly like an idiot. Sitting atop the corpse of a giant undead moth, the Soulbound of the craziest Progenitor continued to laugh by herself, relaxing completely for the first time in years. Later, she knew, the anger and fears would come back, but right now, next to her friend, a merry sociopath blissfully asleep in a literal bloodbath, Athena couldn’t help but think none of her worries really mattered.
A loud moan resounded in the cave and a smirking dhampir stood up, licking her bloodied lips and testing her recently restored shoulder. A loud punch resounded in the cave and a still smirking dhampir fell flat on her ass, rubbing her painful abdomen.
Victoria pouted ostensibly and let herself fall backwards, fixing the ceiling and hugging herself lovingly.
With a swift and inelegant roll, Victoria put herself out of reach from a fist that instead, in a splatter of moth blood, left a deep indentation in the stone ground.
The Shieldbearer threw her a sidelong glance, before resuming her observation of the destroyed surroundings, apparently in deep thoughts and trying to recall something. Victoria eructed a strange noised which, to the trained ear, could easily be mistaken for the cry of pain of the mandrill being stabbed by a rhinoceros while imitating a zebra. The dhampir nodded fervently, while trying to keep her heart rate under a hundred beats per minute, which was already high for a normal human, let alone for a half-undead. If morphology had permitted it, Victoria’s lower jaw would have collided with the floor right then. With a very pissed growl, Victoria grabbed the tall Shieldbearer by the collar of her plastron, forced her down – thankfully the other didn’t resist – and shut the tall woman up with a languorous kiss.
Athena gulped at the sight of the two slit-pupil of the mostly red jewels stabbing through her skull.
Athena vigorously nodded, her previous assessment of her friend’s unstable mentality noisily recalling itself to her. Athena once again nodded, her face red and almost fuming, and Victoria’s smile broadened, the incident apparently forgotten. Victoria shot a discreet glance towards Athena, and saw that the latter was staring at her feet, her face still close to overheating.
I mean… That’s majorly fucked up… Even I am not THAT narcissistic… But she couldn’t know that.
The question had been idle, yet Victoria was surprised to discover that the copper-headed woman’s face could rise another shade of red. No… I’d prefer if you kept your distances if I really lose it… But… Oh well, I guess it’s fine. The only reason why Athena was acting so flustered was a mix of surprise, confused feelings, being on the receiving end of the aforementioned skinship, as well as the remnants of her earlier unusual laughing outburst and a few other circumstantial variables. After some time, the dhampir’s face turned serious and she distanced herself from the tall woman. After the mist dissipated, the Shieldbearer discovered that both of them were as clean as if they had just stepped out of a bath, except they weren’t even wet. Victoria’s eyes suddenly became vitreous and her body slumped down like a marionette whose strings had been cut. Today was Saturday morning and, depressed by Dorothy’s fate, Nicolas had barely slept since Thursday, only making short pauses to eat and stretch a bit. Shaking off the drowsiness, Nicolas trotted towards the kitchen and took a bottle of Coke out of the fridge. The dhampir narrowed her dichromatic eyes, the pupil once again twitching from round to slit and red taking over its blue encirlement.
Once again, the cave shook, this time filled with the cacophony of a surreal fight between a teleporting ghost fleeing for his unlife, a pale dhampir Princess throwing [Soul Blasts] randomly and laughing like a maniac, and a roaring stuffed puppy breathing ethereal fire while trying to bite the crotch of the aforementioned ghost.
Standing still in the middle of the ongoing mayhem, like an unshakeable beacon in a storm, a tall copper-headed woman lifted her amber eyes towards the ceiling and sighed, yet a small half-smile was floating on her lips. Thanks for the chapter by the way i want this story to keep going on and all but by any chance yo planed some sort of ending (rly doubting it )? My personal favorite moment of this story from now on, is from the point on where Athena mentioned "Elric Walker" until the part where Victoria logged out. EDIT: Hey, now that I think about it, is the title a joke of the saying of getting butterflies in your stomach? Motion at constant speed is clearly a very special case, and in practice bodies change their speed with time. His resulting General Theory of Relativity, over ten years in the making (it was published in 1916), has been called the greatest contribution to science by a single human mind. Newton’s theory (permanently linked, at least in the popular mind, with his observation of an apple falling from a tree) stated that every massive body exerts an attractive force on every other massive body, a force which is proportional to the product of the two masses and inversely proportional to the square of the distance between the bodies.
This “inverse-square law” is quite sophisticated enough to explain why a cannonball fired horizontally travels further before hitting the ground the faster it is launched, why a certain minimum speed (about 11.2 kilometres per second) would be required to allow objects to break out of Earth’s gravity and into orbit and why the planets travel in an elliptical orbit around the Sun (although not quite sophisticated enough to predict the slight anomaly in Mercury’s orbit).
Although it is a very weak force (feebler than the other fundamental forces which govern the sub-atomic world by a factor of 1036 or 1,000,000,000,000,000,000,000,000,000,000,000,000), it is a cumulative and consistent force which acts on everything and can act over large distances. Galileo’s famous (and probably apocryphal) experiment involving the dropping of two balls of different masses from the Leaning Tower of Pisa was repeated with even more dramatic results in 1972 when a hammer and a feather were dropped together on the airless Moon and, just as Galileo had predicted, both hit the ground together. Furthermore, Newton had assumed that the force of gravity was purely generated by mass, whereas Einstein had shown that all forms of energy had effective mass and must therefore also be sources of gravity. He realized that if he were to fall freely in a gravitational field (such as a skydiver before opening his parachute, or a person in an elevator when its cable breaks), he would be unable to feel his own weight, a rather remarkable insight in 1907, many years before the idea of freefall of astronauts in space became commonplace. That, and the feeling of his feet being glued to the ground just as they would be in Earth’s gravity, would be enough to convince the astronaut that the acceleration of the spaceship was indistinguishable from the pull of gravity on the Earth. As Einstein predicted, the closer a body is to a large mass, with a commensurately large gravitational pull, the slower time runs for it. With modern atomic clocks of sufficient accuracy, differences in the passage of time at different altitudes above sea level (and therefore different distances from the Earth's centre of gravity) can be measured, and even the tiny differences due to the changing shape of the Earth as the tidal force of the Moon pulls and stretches it. Or, perhaps a better way of looking at it, gravity is a kind of inertial force, in the same way as the so-called centrifugal force is not a force in itself, merely the effect of a body’s inertia when forced into a circular path. Electrons have a negative charge, protons have a positive charge and neutrons have a neutral charge. Electric force is much stronger  than the gravitational force, but because most macro sized objects have equal numbers of protons and electrons, we rarely see its effects on a large scale. Atoms are composed of a positively charged nucleus, surrounded by negatively charged electrons.
For example for light eminating from a single source in all directions, its intensity is four times less when you are twice as far away from it. Estimate the gravitational force of attraction between two people sitting side by side on a park bench. It is simply a constant of proportionality that allows us to use our conventional units for charge and force. It can be replaced with er, relative permittivity when the medium separating two charges isn't free space. Each electron is moving thus you have electricity and because there is electricity there is also magnetism. We must remember that the movement of negative electrical charge is in the opposite direction to conventional current and account for this when we solve problems involving moving charges.

Displaying her amazing memory and psychomotricity, she continued to run backwards while avoiding obstacles. She thus found herself hanging far above ground… and fighting her usual desire to let go to count the seconds until *splarsh*.


She nevertheless casted a curious glance downwards, and witnessed the unsightly appearance of a very pissed Monarch. Well, the poor bastard had been trying its earnest to obliterate the two adventuress, yet they kept ignoring its attempts and only ran all over the place while discussing game mechanics without a care in the world. After taking the place of Victoria mid-air, she had latched onto the rock, executed a backflip, thrown herself upwards, did another flip, and dropkicked the improvised spike down with all her might, thus both accelerating the monstrous stabbing apparatus and reducing her own momentum.
She was unable to see, however the sounds she perceived nevertheless told her that Monarch had yet to bite the dust… figuratively speaking. She mentally made it thinner and longer, piercing deeper and deeper until a startled cry from above informed her she had dug her way to the top. A torrent of blood poured onto Victoria, but she was thankful because it hid the intense blushing that had invaded her face from having named her attack herself. Athena’s eyes widened and her gaze fell back on the pale unconscious girl and her stupid grin. She then began scanning their surroundings for potential unexpected threats, something that had become akin to a reflex to her. Athena however, totally oblivious to her friend’s dumbfounded state, was rambling on her own while blushing furiously.
The pale girl was clearly smiling, yet only killing intent emanated from her beautiful face. However, behind her happy and calm facade, the Progenitor was in thoughts bashing her head against a wall. In fact, it was rather disturbing to see the mighty Athena act with mimics that clearly would have best suited the bookworm Eva. She was actually relieved that she was still somehow friend-zoned, even after that impromptu saliva exchange earlier. The act of kissing in itself wasn’t really weighting on her mind, nor was she reading much into it. Athena followed, observing the surroundings and warily sending regular glances at the dhampir who had adopted her feared thinking pose and was muttering to herself. Their equipment too had been scrubbed of all the blood, dust and bodily fragments that had covered it.
The Shieldbearer rushed to catch her, internally grumbling that her reaction time was being thoroughly trained with a friend like that.
After Athena’s return, the adrenaline had kept Victoria going, but the human behind the dhampir knew his true body wouldn’t hold up much longer. He drank just enough to restart his engine, but without risking to be forcefully disconnected by his W-Chair for “physiologic emergency” – a pretty useful feature though – and then jumped on his sofa, scarring the Ever-Napping King McLeon to death. It was glorious, and the sheer stupidity, weirdness and chaos of it all had my head hurt in a futile attempt to understand what I was reading while I laughed.
You know, we had butterflies (something close enough) stomachs, and maybe that could be linked to the way victoria killed it. Einstein wanted to generalize his theory to consider how a person sees another person who is accelerating relative to them.
So, even though gravity can be effectively ignored by chemists studying how groups of atoms bond together, for bodies more massive than the planet Jupiter the effects of gravity overwhelm the other forces, and it is largely responsible for building the large-scale structures in the universe.
A real-life example of gravitational time dilation can be seen in GPS systems in geo-synchronous orbits above the Earth, which need to constantly adjust their clocks to account for time differences due to the weaker gravity they experience compared to that on the Earth's surface (it is estimated that their accuracy would be out by as much as 10 kilometers a day without this adjustment). In order to rationalize this situation, though, Einstein was to turn our whole conception of space on its head, as we will see in the next section.
Because everything else is made up protons, electrons and neutrons they also have electrical charge. Protons are about 1800 times more massive than electrons, but carry the same amount of charge (only positive). How does this force compare with the gravitational force exerted on them by the Earth, i.e. Typically a score when employed with Ease And Convenience Of A Cash Advance Ease And Convenience Of A Cash Advance mortgage payment or office.
They have ability to solve your toughest problems and questions from any level of complexity in gravitation. Though they lacked the cake, the dhampir was vaguely confident that the monster wouldn’t complain if she stuck it in its back. Dark orange-red blood was splattering all over the place, and especially on the tall copper-headed woman in black armour who was straddling the moth’s thorax, holding both its antennas in her left gauntlet and meticulously pummelling its eyes with her right. Victoria was now sleeping peacefully on the stone floor, in a pool of gore and blood, surrounded by chaos and death.
Then, as soon as she was convinced Athena wouldn’t start talking again, the Princess released her lips, but not her armour, and glared angrily in her amber eyes. Truth be told however, the pale “girl” couldn’t have known – a fact that probably saved Nicolas’ already moribund male pride – that Eva’s experience in skinship vastly outstripped her own.
She usually took more notice of people’s words than their actions, contrary to Victoria who rarely listened to what others said but always liked to interpret every small gestures, especially her own. Athena’s heart skipped a beat, but as promised nothing dangerous happened, if not for the discomfort of being rubbed all over her body at once. However he didn’t select any thread and instead went to his inbox to write a private message. Thus, gravity squeezes together massive bodies like our own Sun, and it is only the explosive outward energy in the Sun’s ultra-hot core that holds it in hydrostatic equilibrium and stops it from collapsing into a super-dense white dwarf star.

Nope… just a passing bat – the dhampir screamed with… undeniable courage… all the while cursing whoever reckless imbecile came up with this joke of a plan. I, the Official Narrator… aka Narra-kun apparently… is back… Great, now everybody will be confused about the limits of the world… Please just forget what you just read. Her new weapon was actually too heavy for her to lift, but since it was half-levitating, she managed.
For example, if a spaceship were to orbit close enough (but not too close!) to a hugely massive object such as a supermassive black hole, the gravitational effects may be significant enough to slow down time for the occupants compared to elsewhere, effectively allowing them to travel into the future.
