Question

The nature of the acceleration vs displacement graph for a particle is executing S.H.M. is

Assertion: Simple harmonic motion is a uniform motion. Reason: Simple harmonic motion occurs due to gravitational force only.

Assertion: The graph between velocity and displacement for a harmonic oscillator is a parabola. Reason: Velocity remains constant throughout the motion in simple harmonic motion.

Displacement versus time curve for a particle executing S.H.M. is shown in figure. Identify the points marked along the time axis at which (i) velocity of the oscillator is zero, (ii) speed of the oscillator is maximum.
