Question

potential energy is stored energy, while kinetic energy is energy of motion.
in the diagram below, when the swing is stopped at point a it has the most potential energy. as the swing moves, the potential energy changes to kinetic energy through point b and it has the greatest amount of kinetic energy at point c.
where does the swing have the least potential energy?
point b
point a
point c

Explanation:

Step1: Recall potential energy concept

Potential energy is related to height. Lower height means less potential energy.

Step2: Analyze points in diagram

Point C is the lowest - most point of the swing's motion.

Answer:

C. Point C
