Question

Define frequency of Rotational Motion ? ​

Answer 1

$\huge\underline\green{\sf Frequency:-}$

Number of revolution described by Particle per second is its frequency.

Its unit is Revolution per second (rps)

or Revolution per minute (rpm)

$\large\red{\boxed{\sf NOTE :- 1rps = 60 rpm}}$

Answer 2

If we assume an object is continuously rotating, then another way to look at rotational motion is to examine the period of rotation, T.

Frequency: Frequency (ν) is the number of complete oscillations or vibrations in 1 s. It is the inverse of time period (T).

So, the frequency is,

V = 1/t

Unit of frequency is s-1 or Hz (Hertz).

Time period is the time taken to complete one oscillation. It is measured in second, s.
