what is potential Energy ?

When a body is projected vertically up. At some point P at height h its kinetic energy is twice of potential energy at that point. At what height its potential energy is twice that of kinetic energy?

When a spring is compressed or stretched, what happens to its potential energy?

What is gravitational potential energy ?

An artificial satellite moves in a circular orbit around the earth. Total energy of the satellite is E. Then what is the potential energy of satellite

When an air bubble rises in water, what happens to its potential energy /

What ids gravitational potential energy ? Obtain an expression for it in case of a body of mass m and at a height h above the Earth's surface.

The K.E. of a satellite moving in a circular orbit around a planet is 1.5xx 10^(10)J . What is its potential energy?

When a ball is hung from a vertical spring, it stretches the spring. As it drops, it loses gravitational potential energy , but this does not at all show up as kinetic energy. What happens to the gravitational potential energy ?
