What happens to the potential energy if the height of a body is doubled?

What will be the potential energy of a body when its mass becomes doubled.

What happens to the potential energy of the molecules when a solid body is compressed ?

What happens to the total energy of a freely - falling body when it strikes the ground ?

(a) Compare the kinetic energies of two identical bodies, one moving north and the other moving south with same speed. (b) What happens to the kinetic energy of an object if its mass in doubled while its velocity remains the same

Show that the potential energy of a body raised vertically to a height h is the same as the potential energy of the body raised to the same height along a smooth inclined plane.

What will happen to potential energy of a spring when it is compressed ?
