Gravity is a non-contact force (a force that can be exerted on a body without touching it), one of four fundamental non-contact forces we know of. The latter two are active only at distances as small as those present between protons and neutrons in the nuclei of atoms. Isaac Newton and others determined, mostly from astronomical data — observations of the motions of planets in the sky — that the gravitational attraction is a property of mass, that it is proportional to the product of the two masses involved, and that it is inversely proportional to the square of the distance between their centers of mass.
The graph on the right shows how the force of gravity (Fg) varies as one of the masses is increased from zero and the other is held constant.
We generally think of gravity in terms of one variable mass and one fixed mass, like a planet. The universal law of gravitation is called an inverse-square law because the force is inversely proportional to the square of the distance between two masses. The important thing about this feature of gravity is that if we double the distance between objects, the force of gravity is reduced by a factor of four (22), not two.
Orbiting is a perfect balance between inertia, the tendency of a body to move in a straight line (not a curve) until acted upon by a force, and the attractive force of gravity. As the Moon orbits Earth, it has inertia, which always moves it in a direction tangential to the orbital path (nearly a circle). Only a centripetal (center-seeking) force, like gravity, is required to keep bodies in orbit around one another. Here's another way to think about it: Imagine you've got quite an arm (QUITE an arm), and can throw a baseball very fast.
Look at these two scenarios (left) First, you throw the ball at a velocity that produces a forward distance in a given time (let's say a second) that does not keep up with the downward distance caused by the pull of gravity.
Now imagine that you throw the ball with sufficient speed that the curvature of Earth gives it enough extra height in any given period of time that the amount of distance it falls due to gravity is just enough to keep it a fixed distance away from the ground. That's really quite a speed, and it partly explains why it's so difficult to get objects to orbit Earth. A 3 Kg newborn baby at the surface of Earth is gravitationally attracted to Earth with a force of about 30N.
Calculate the weight, in Newtons and in pounds, of the Mars curiosity rover, which has a mass of 899 Kg, on both Earth and Mars. How far apart (in meters) must two 1000 Kg spherical masses be in order to exert a 0.01 N force on each other?
We can use the universal law of gravitation to find the acceleration of gravity near the surface of Earth (below). This is a good derivation to practice your skills with scientific notation and cancelling units. Notice that 9.8 mA·s-2 is the acceleration of gravity near the surface of Earth, where r = the radius of Earth.

In 1687, Isaac Newton combined his observations with theories from other scientists about gravity and gravitation into a scientific law: the Law of Universal Gravitation. The force of attraction between two masses is defined by the Universal Gravitation Equation. Scientists and philosophers from ancient times have made observations about gravity on Earth. In studying the orbits of planets around the Sun, Kepler determined that gravitational attraction varied with separation, while formulating his Laws of Planetary Motion.
In 1687, Isaac Newton's observations on planetary motion and empirical measurements, allowed him to establish the Law of Universal Gravitation, which was explained in the publication of Philosophiæ Naturalis Principia Mathematica (or simply Principia) set of three books that stated his Laws of Motion, the Law of Universal Gravitation and a derivation of Kepler's Laws of Planetary Motion. The story that Newton was sitting under a tree when he was hit in the head by a falling apple, thus causing him to discover gravity, is a fable.
The Law of Universal Gravitation states that every object of mass in the Universe attracts every other object of mass with a force which is directly proportional to the product of their masses and inversely proportional to the square of the separation between their centers. Note: Newton's Law of Universal Gravitation is sometimes incorrectly called the Theory of Universal Gravitation. Note: Also, the Law of Universal Gravitation is sometimes called the Universal Law of Gravitation. Newton could not explain the mechanism of how and why gravitation occurred, except that it was some sort of force at a distance. From the Law of Universal Gravitation, Newton formulated the Universal Gravitation Equation, which defines the gravitational force between two objects. Application of this equation is especially useful in determining the orbits of celestial objects, such as that of the planets around the Sun.
However, in most cases there are more than two objects involved, which can result in some complicated mathematics.
For example, the motion of the planet Mars around the Sun is not only determined by the masses of Mars and the Sun but also by the influence of the gravitation from Mar's moons, the Earth and other planets.
Predictions of the orbit of the planet Mercury proved to be slightly inaccurate using the Law of Universal Gravitation. Electromagnetic waves or light rays are deflected by gravitation, especially when they pass by a large mass, such as the Sun. The Law of Universal Gravitation requires that the gravitational force is transmitted instantaneously over large distances to maintain stability in planetary and stellar orbits.
This implies that what is called the speed of gravitation (also carelessly called the speed of gravity) is infinite. Solutions to these problems were finally found in Einstein's Theory of General Relativity that he published in 1915. Since ancient times, scientists and philosophers studied gravity and then later gravitation. Please include it as a link on your website or as a reference in your report, document, or thesis.
If we bring a negative and a positive charge together, the electrostatic force is attractive (brings them together). You can think of such constants as fixed numbers that are there for us to get the units correct. The force of gravity is greater on a more massive person than a less massive person, therefore the more massive person weighs more — weight, unlike mass, is a measure of force.
The graph shows that when r, the distance between masses, is small, the gravitational force is high, but as r is increased, the force drops non-linearly. This idea underscores the notion that for a long time observers were stuck on the idea that there must be some force pushing in the direction of the motion.
But for every bit of tangential motion, there is some inward motion that keeps the path bent exactly to the orbital path.

How fast would you need to throw it so that as it travels, the bending away of the spherical Earth below it is just balanced by the downward distance it is pulled by gravity — it orbits just above the surface? The forward inertia of the ball keeps it moving forward and gravity bends that path into a curve (an ellipse, actually). Generally when we fire off a satellite, the rocket that carries it accelerates straight upward until it clears most of the friction-producing atmosphere, then turns over to accelerate to a tangential velocity that is fast enough to achieve a stable orbit. Remember that ever body in the universe exerts a mass-proportional amount of gravity on every other body. The location of the center of mass of the Earth-Moon system (the point where the two, if joined by a stick, would balance) is somewhere inside of Earth because Earth has about 6 time the mass of the moon.
The dashed circle stays where it was at the beginning to help you see the circular motion of the larger planet. If we travel a substantial distance from the surface of Earth (it has to be big because r is so large), we would expect the acceleration of gravity to be smaller.

This law states that the mass of an object is attracted toward the mass of other objects by a force called gravitation. Although the law and its equation were effective in predicting many phenomena, several discrepancies later arose in astronomical measurements. Although he may have been inspired by seeing an apple fall from a tree, his studies and correspondence with other scientists who were studying gravitation probably influenced him more than seeing an apple fall.
However, it was shown that the gravitation from a large uniform sphere is approximately the same as if all the mass was concentrated at its center.
Critics said that this explanation was bringing the occult or mysticism into science, which Newton denied. The result is that orbit of Mars includes perturbations or deviations caused by the other planets. However, calculations from Newton's law result in only one-half of the deflection that is actually observed by astronomers. Although light from the Sun may take eight minutes to reach the Earth, gravitational changes would have to occur immediately to maintain orbital stability between the two objects.
Isaac Newton formalized the observations into a scientific law: the Law of Universal Gravitation, which states that states that all objects of mass are attracted toward other objects of mass, due to a force called gravitation.
Although the law and its equation were effective in predicting many phenomena, several discrepancies arose in measurements that were made. But if we bring two positive charges or two negative charges together, they repel one another (opposites attract, likes repel).
That makes sense, of course: If there's a baby carriage moving down the street, we pretty much expect the force to be applied from behind, not from the side. Thus while Earth exerts a force on the Moon that keeps it in orbit, the Moon also exerts a force on Earth. Think of a seesaw: Where does the light person need to be in order to balance the weight of a heavy person? It wasn't until 1915 that Einstein's Theory of General Relativity provided a solution to these discrepancies. In the 1600s, Galileo Galilei, Robert Hooke and Johannes Kepler formulated laws of gravity near the Earth. On the other hand, universal gravitation implies that gravitation is throughout the universe, which is slightly different than a universal law. Einstein's Theory of General Relativity provided a solution to the Universal Gravitation problems. There is no such repulsive component to the gravitational force; you never see someone walking down the street suddenly be ejected from the planet by gravity. The Law of Universal Gravitation only makes predictions of how bodies are attracted and does not explain why it happens.
