29th Jan, 2021
Rotational motion or circular motion can be analyzed in the same way of linear motion. For example, Uniform circular motion is one of the rotational motion.
In uniform circular motion speed of the object is always constant and direct rotational motion imagination is changing and as a result object has acceleration.
Tangential Velocity:
V=2πr/time where r is the radius of the motion path and T is the period of the motion
AngularVelocity;
ω=2π/T=2πf where T is the period of the motion and f is the frequency
Hope that's helpful
Best of luck
