What is the definition of SHM?
Periodic motion without loss of energy in which the acceleration of a body is directly proportional to its displacement and is directed towards the equilibrium position but in opposite direction of the displacement.
Periodic motion without loss of energy in which the acceleration is directly proportional to its velocity and is directed towards the equilibrium position but in opposite direction of the velocity.
Periodic motion without loss of energy in which the acceleration of a body is inversely proportional to its displacement.
