What is angular displacement? |
Angular displacement is the angle substended by the arc , defined by Theta=s/r |
|
|
What is angular velocity? |
Angular velocity (omega,cursive w) of the object is the rate of change of angular displacement with respect to time. w=theta/t For 1 complete revolution, w=2pi/T T is period of object, 2pi is angular displacement |

What is linear velocity? |
Lineat velocity, v, of an object is its instantaneous velocity at any point in its circular path v= arc length / time taken =r(theta)/t v=rw |
