Arocket moves away from the surface of earth. as the distance r from the center of the earth the planet increases, what happens to the force of the gravity on the rocket?

The force of gravity will decrease.
More the distance between the objects, less the force of gravity between them.
They are inversely related.
Hope this help :)

W= fd
where f is an applied force and d is the distance over which it is applied. when a parachuting skydiver is at constant velocity, he is experiencing "terminal velocity", the point at which his acceleration down is canceled out by air resistance. that means that the resisting force of the air is equal to his weight, but in the opposite direction. with this, we can solve for the work done by the force.
w = fd
w = (92.0)(9.81 m/s^2) (325)
w= 2.93 x 10^5 j
the value for work in this case is positive because it is pushing up on the skydiver, who has a downward force of gravity.
therefore the answer is 2.93 x 10^5 j
