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?

A)
The spring has kinetic energy and the hands have kinetic energy.


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


C)
The spring has potential energy and the hands have potential energy.


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

Answer 1

the answer is D

Step-by-step explanation:

Answer 2

D

Step-by-step explanation:

When the spring is wound, then it gathers potential energy in the form of tension energy. As it slowly unwinds, the potential energy is converted to kinetic energy of the hands' movements of the clock. This energy is channeled through the use of cogs/gears in the clock.
