Question

find the expression for velocity of SHM​

Answer 1

Let there be a simple harmonic motion whose displacement is given as
x = A sin wt
where x is displacement from mean position
A = Amplitude of oscillation
w = angular frequency of the oscillation
t = time

So, differentiation of equation on both sides with respect to time
We get,
dx / dt = A cos wt * d(wt)/dt = Aw cos wt.....(chain rule)
Therefore,
velocity (v) = Aw cos wt
