Question

Why angular velocity is also known as angular frequency? ​

Answer 1

Answer:

Explanation:Angular frequency ω (in radians per second), is larger than frequency ν (in cycles per second, also called Hz), by a factor of 2π. This figure uses the symbol ν, rather than f to denote frequency. A sphere rotating around an axis. Points farther from the axis move faster, satisfying ω=v/r.

Answer 2

Angular Velocity = ∅/t = rate of change of Angular displacement (∅).

Now, 1/t is also known as frequency(f).

Therefore, Angular Velocity can also be written as ∅/t = ∅(f)

So, as it can be seen from the above relation that Angular Velocity is ∅(f) i.e., Angular Displacement multiplied with frequency.

That is why, Angular velocity is also called Angular Frequency.
