Question

which image shows both potential and kinetic energy?

Explanation:

Potential energy is energy due to position (e.g., height), and kinetic energy is energy of motion (velocity). The first image (pendulum at lowest point) has only kinetic (no height - max speed). The third image (pendulum at highest point) has only potential (instantaneous stop - max height). The middle image (pendulum in - between) has both: some height (potential) and some speed (kinetic).

Answer:

The middle - image (pendulum in motion, not at extreme or lowest point) shows both potential and kinetic energy.
