Question

What is phase difference between the displacement and velocity in a simple harmonic motion?

Answer 1

Answer:

Explanation:

Displacement in SHM is given by x = A sin( wt) where A is amplitude, w is angular velocity, t is instantaneous time. Phase difference between sin and cos function is 90 degrees or pi/2 radians . Hence phase difference between displacement and velocity is 90 degrees or pi/2 radians.
