Question

Wired Faculty App

Define angular displacement displacement, angular velocity and angular acceleration.

Solution

Angular displacement is defined as the angle described by particle about the axis of rotation. It is represented by $straight theta$ .
Angular velocity is defined as the rate of change of angular position.
It is represented by $straight omega comma$
Mathematically it is given by, $straight omega equals dθ over dt$
Angular acceleration is the rate of change of angular velocity.
It is represented by a.
Mathematically it is, $straight alpha equals dω over dt$
