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 is it initially released. At which point in the diagram is all of the energy gravitational potential energy?(1 point)

Responses

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

just after release of the swing
just after release of the swing

at the highest point as the swing moves forward
at the highest point as the swing moves forward

when the swing is pulled back prior to release

None of the responses are correct. The point at which all of the energy is gravitational potential energy is "when the swing is pulled back prior to release."
