A student takes a simple pendulum. When the bob is displaced from rest and then released, it begins to move back and forth as shown in the figure below. The graph below shows the kinetic and potential energies of the pendulum at various positions. What change in the kinetic energy and potential energy can be explained based on this?
Potential energy changes to kinetic energy when the pendulum moves from Q to R.
Potential energy changes to kinetic energy when the pendulum moves from R to Q.
Kinetic energy changes to potential energy when the pendulum moves from Q to S.
Kinetic energy changes to potential energy when the pendulum moves from Q to R.
