Question

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

Assertion: Acceleration is proportional to the displacement. This condition is not sufficient for motion in simple harmonic. Reason: In simple harmonic motion direction of displacement is also considered.

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.
