Question

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?

Responses

as the released swing begins moving backward
as the released swing begins moving backward

Just after the swing is released
Just after the swing is released

when the swing is pulled back prior to release
when the swing is pulled back prior to release

at the highest point as the swing is moving forward

Answer 1

when the swing is pulled back prior to release

At that highest position the speed is zero, so kinetic energy is zero and all the mechanical energy (relative to the lowest point) is gravitational potential energy.
