Answer:
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 zero.
According to the principle of conservation of mechanical energy, the total kinetic energy any point is equal to the total potential energy.
M.A = K.E + P.E
As the kinetic energy of the bob decreases, the potential energy increases and becomes maximum when the velocity is zero.
Also, as the potential energy of the bob decreases, the kinetic energy increases, and becomes maximum when the displacement is zero
Thus, we can conclude that, 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 zero.
