Which graph in SHM shows the K.E of a body:

Explanation

Kinetic Energy (K.E.): The kinetic energy of a body undergoing SHM varies sinusoidally with time. It is maximum at the equilibrium position (where velocity is maximum) and decreases to zero at the extreme positions (where velocity is zero).Potential Energy (P.E.): The potential energy of a body undergoing SHM is directly related to its displacement from the equilibrium position. It is maximum at the extreme positions (where displacement is maximum) and decreases to zero at the equilibrium position (where displacement is zero).Total Mechanical Energy (E): The total mechanical energy of a body undergoing SHM remains constant throughout the motion if there are no external dissipative forces (such as friction). It is the sum of kinetic energy and potential energy at any point in time.
