Question

An old clock has a spring that must be wound to make the clock hands move. Which statement describes the energy of the spring and hands of the clock?

Answer 1

When the spring is wound up, it posseses elastic Potential energy since it is in it's compressed state. As the spring unwinds, the potential enery of the spring changes to the kinetic energy of the hands of the clock, which make them move.

Answer 2

The spring has potential energy and the hands have kinetic energy.
