• If we take one of the objects to be fixed, the work done by gravity in moving the other object from distance r1 to r2 is and the work done to move it back to r2 is • So we see that the work done for a round trip from r1 to r2 and back is 0 2 1 12 d r r W =F r r () 1 2 2 1 21 d d 12 r r r r W =F r r =−F r r =−W Gravity is a conservative force, so we can define a potential energy associated with itNewton's law of universal gravitation states that there is a gravitational force between any two masses that is equal in magnitude for each mass, and is aligned to draw the two masses toward each other The formula is F = G m 1 m 2 r 2 {\displaystyle F=G {\frac {m_ {1}m_ {2}} {r^ {2}}}\ } · Gravitational Potential energy Gravitational potential energy is that an object has due to its height or vertical position Also, the energy is stored consequently of the gravitational attraction of the earth for the object In the same way, the gravitational potential energy of a massive wrecking ball de...
