An illustration of a pendulum at 3 positions of a pendulum. The equilibrium position is labeled B. The other two positions are the maximum displacement of the pendulum labeled A and C. In between A and B are 3 lighter colored pendulum sketches equally spaced. In between B and C are 3 lighter colored pendulum sketches equally spaced.
At which point or points does the pendulum have the greatest kinetic energy?

A only
B only
C only
both A and C

B only.

Explanation: gravitational potential energy is largest at the extreme positions A and C, where the pendulum's speed is zero, so kinetic energy is zero. At the equilibrium (B) the bob is fastest, so kinetic energy is greatest (by energy conservation, potential lost → kinetic gained).
