A diagram is drawn showing a swing set with a swing pulled backward prior to release. The diagram shows how the swing will move forward and then backward after it is initially released. At which point in the diagram is all of the energy gravitational potential energy?

A) as the released swing begins moving backward

B) at the highest point as the swing moves forward

C) when the swing is pulled back prior to release

D) just after release of the swing

Respuesta :

Answer:C) When the swing is pulled back to prior release

Explanation:

This question involves the concepts of the law of conservation of energy, gravitational potential energy, and kinetic energy.

All of the energy is gravitational potential energy at "C) when the swing is pulled back prior to release".

The law of conservation of energy states that at any point the total energy of the swing must be constant, which means:

Total Energy = Gravitational Potential Energy + Kinetic Energy = Constant

It is clear that the swing has a non-zero speed in all given situations except the situation in part C), where the swing is at rest before release. Since the kinetic energy exists due to motion in the object. Hence, the kinetic energy will be zero when the swing is pulled back prior to release. It means all the energy in the swing at this time will be the gravitational potential energy.
