(a) Kinetic energy. (b) Potential energy. (c) Potential energy. (d) Kinetic energy. (e) Kinetic energy. (f) Potential energy.
Work Step by Step
There is movement/motion in (a), (d) and (e). Thus, they illustrate kinetic energy. In the other examples, (b), (c) and (f), the energy is stored, and can be converted into kinetic energy, thus, they illustrate potential energy.
