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?(1 point)
Responses

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

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

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

at the highest point as the swing moves forward

Answer 1

When the swing is pulled back prior to release.

At that highest point the speed is zero, so kinetic energy is zero and (neglecting losses) all the mechanical energy is gravitational potential energy.
