What example demonstrates an object that has potential and kinetic energy?

Question

Question 2 options:

A pendulum swinging back and forth

A race horse at the starting line

A ball at the top of the hill

A car at a stop sign waiting to go

Answer 1

The best example that demonstrates an object that has both potential and kinetic energy is:

A pendulum swinging back and forth.

In this scenario, the pendulum has potential energy when it is at its highest points (the endpoints of the swing) and kinetic energy when it is at its lowest point (the midpoint of the swing). This allows it to exhibit both forms of energy as it moves back and forth.

While the ball at the top of the hill does have potential energy, it has kinetic energy only when it starts to roll down. The other options do not effectively demonstrate both kinetic and potential energy in the same manner during their respective states.
