Question

the ball has potential energy when
□ it is at the highest point and when it is compressed at its lowest point
□ it is moving

Explanation:

Potential energy (PE) relates to an object's position or state. Gravitational PE depends on height (\(PE_{grav}=mgh\), \(m\) mass, \(g\) gravity, \(h\) height), so at the highest point, gravitational PE is maximum. Elastic PE depends on deformation (\(PE_{elastic}=\frac{1}{2}kx^2\), \(k\) spring constant, \(x\) displacement), so a compressed ball at the lowest point has elastic PE. "It is moving" refers to kinetic energy (\(KE = \frac{1}{2}mv^2\), \(v\) velocity), not potential. Thus, the first option is correct.

Answer:

it is at the highest point and when it is compressed at it's lowest point
