The kinetic energy of the bob on a simple pendulum swinging in simple harmonic motion has its maximum value when the displacement from equilibrium is at what point in its swing?
A)zero displacement
B)1/4 the amplitude
C)1/2 the amplitude
D)equal the amplitude

Question

The kinetic energy of a pendulum is maximum at the equilibrium position (zero displacement) because this is where its speed is highest. At the equilibrium point, all the potential energy has been converted into kinetic energy.
