Question
A child is swinging back and forth. At which point(s) during the swing is potential energy at its highest, and at which point(s) is kinetic energy at its highest?(1 point)
Responses
Potential energy is highest at the bottom of the swing; kinetic energy is highest at the top.

Potential energy is highest at the highest points of the swing; kinetic energy is highest at the bottom of the swing. (Choice C)
Explanation: At the highest points the child has maximum height (largest gravitational potential energy mgh). At the bottom the speed is greatest so kinetic energy (½mv²) is highest.
