A particle of mass m oscillates with simple harmonic motion between points x1​ and x2​, the equilibrium position being O. Its potential energy is plotted. It will be as given below in the graph:

A particle executing harmonic motion is having velocities v1 and v2 at distances is x1 and x2 from the equilibrium position. The amplitude of the motion is

A particle is executing simple harmonic motion with a time period T. At time t = 0, it is at its position of equilibrium. The kinetic energy-time graph of the particle will look like
