The phase difference between the instantaneous velocity and acceleration of a particle executing simple harmonic motion is
Options
(a) π
(b) 0.707π
(c) zero
(d) 0.5π
Correct Answer:
0.5π
Explanation:
Let y = A sin ωt
vinst = dy/ dt = Aω cos ωt
vinst = Aω² sin (ωt + π/2)
Acceleration = – Aω² sin ωt = Aω²sin (π + ωt)
ɸ = π/2 = 0.5 π.
