A simple pendulum bob oscillates with small amplitude in air, experiencing light viscous damping. The lowest point of the swing is chosen as the reference level for zero gravitational potential energy.

Damped simple pendulum

Which of the following statements is/are correct?

  1. The damping force is zero when the kinetic energy of the bob is maximum.
  2. The damping force and the restoring force point in the same direction when the bob is moving away from its equilibrium position.
  3. The magnitude of the damping force is maximum when the gravitational potential energy of the bob is minimum.
