A block of wood loses 100 J of gravitational potential energy as it slides down a ramp. If it has 90 J of kinetic energy at the bottom of the ramp, what can you conclude ?

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 ?
