what are two ways an object can gain more gravitational potential energy

In deep space, sphere A of mass 30 kg is located at the origin of an x axis and sphere B of mass 10 kg is located on the axis at x = 0.85 m. Sphere B is released from rest while sphere A is held at the origin. (a) What is the gravitational potential energy of the two-sphere system just as B is released? (b) What is the kinetic energy of B when it has moved 0.25 m toward A? Additional Materials eBook Powers of Ten

A satellite on a circular low Earth orbit moves at a constant speed and is subject to the gravitational force of the Earth. Is there any work done on the satellite. Explain your answer.

Calculate the minimum amount of work needed to move a 400 kg rocket from Earth's surface to the International Space Station in orbit 300,000 m above Earths surface. Solve for the minimum amount of work needed to move the payload to the ISS. Start with general equations and explain what you are doing and why you did what you did. Evaluate your solution. Describe how you evaluated your answer and whether or not you think your answer is reasonable.
