Question

what is the phase diffrence between acceleration and velocity?​

Answer 1

The phase relationship between displacement, velocity, and acceleration is that such that velocity is 90° out of phase with accelerationand displacement is 180° out of phase with acceleration. In other words, when displacement is at a maximum, velocity is at a minimum, and acceleration is at a maximum

Answer 2

the phase difference is given below :

-Velocity lags Acceleration by 90 degs.

Displacement lags acceleration by 180 degrees.

Which implies Acceleration leads velocity by 90 degs.
