Question

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

(a) π

(b) 0.707π

(c) Zero

(d) 0.5π

I have been asked this question during an online exam.

I'd like to ask this question from Oscillations topic in portion Oscillations of Engineering Physics I

Answer 1

Correct answer is (c) Zero

For explanation I would say: The phase difference between the instantaneous velocity and acceleration of a particle executing simple harmonic motion is π/2.
