Question

The phase difference between the instantaneous velocity and acceleration of a particle executing simple harmonic motion is

• A. $0.5 \pi$
• B. $\pi$
• C. $0.707 \pi$
• D. zero

Answer 1

Answer: (A)

$0.5 \pi$

Answer 2

The displacement equation of the particle executing SHM is

Acceleration = Aω2sin ωt

the instantaneous velocity and acceleration have a 0.5π phase difference.
