The image shows a pendulum that is released from rest at point A.
An illustration of a pendulum at 5 different positions. The central position, the equilibrium position is labeled C. The two positions on the left are labeled A and B respectively. The two positions on the right are labeled D and E respectively. All positions are equally spaced.
Which pair of labels is correct?
A: Maximum kinetic energy
C: Maximum gravitational potential energy
B: Maximum kinetic energy
D: Maximum gravitational potential energy
A: Maximum gravitational potential energy
C: Maximum kinetic energy
B: Maximum gravitational potential energy
D: Maximum kinetic energy

A: Maximum gravitational potential energy; C: Maximum kinetic energy.
Reason: At the end points (A and E) the bob is at greatest height and momentarily at rest, so gravitational potential is maximal and kinetic is zero. At the lowest point C the bob has its greatest speed (all the lost potential converted to kinetic), so kinetic energy is maximal.
