Question

In Simple Harmonic Motion chapter's formula
x=Asin(wt+phi)
why do we refer to omega (w) as angular frequency and not angular velocity??

Answer 1

I believe it may be due to the fact that:
A) Angular frequency is just the magnitude of angular velocity (i.e. it is the scalar form of angular velocity. In S.H.M, there is no difference between +w and -w (w: omega) as it isn't rotation about a fixed point (in which direction would matter) but rather oscillation along a line.
B) What's more, in simple harmonic motion, the vector quantity of displacement is given by the sine function.

Answer 2

The units of omega are radians/second, so we can refer to omega as angular speed or angular frequency. Frequency refers to cycles/second, but angular frequency refers to radians/second.

Answer 4

ja gand mara bakchod
aaye hai physics padhne aur angular frequency aur angular velocity me diff bhi nai malum SHM ka lecture padh ma ke laude Walter Lewin himself says that we don't have to refer to it as angular velocity but as angular frequency..BAHANCHOD
