.... already been written that we know that wt = 2p when the function x repeats itself
wt + f + 2p = w(t+T) + f
so wT = 2p
so
T = 2p/w
The frequency of the motion is the number of waves that pass a point a specific time or the number of oscillations or cycles the particle makes in a given time. The unit for the frequency is Hertz , cycles/s, or reciprocal seconds s-1. So
F = 1/T = w/2p so w = 2pf = 2p/T
Differentiating it is possible to obtain the equation for the speed of the particle .... |
