Angular velocity and angular frequency

Click For Summary
SUMMARY

The discussion clarifies the distinction between angular velocity and angular frequency. Angular velocity, measured in radians per second (rad/s), refers to the rate of rotation of an object, while angular frequency is defined in the context of oscillatory motion, specifically when a body rotates with constant angular velocity. The relationship between the two is expressed as ω = 2πf, where f represents frequency. Angular velocity pertains to circular motion, whereas angular frequency is associated with sinusoidal oscillations, such as simple harmonic motion and alternating current variations.

Homework Statement




what is the difference between angular velocity and angular frequency?

Homework Equations





The Attempt at a Solution

 
Physics news on Phys.org
if angular velocity is given in radian/s, then it is equivalent to angular frequency, but there is a potential catch... because there is a difference between instantaneous angular velocity and average angular velocity... and one can only define an angular frequency if a body rotates with constant angular velocity. In which case \omega = \frac{d\phi}{dt}=2\pi f
 
Simply put though, one is ascociated with angular motion, circular motion is the most fundamental example.
The other is associated with sinusodial oscillations whether it is simple harmonic motion or variations in alternating current.
 
thanks a lot for replying to my questions
