Question

What is angular acceleration?

Answer 1

Angular acceleration:

1. Rotational acceleration is another name for angular acceleration.
2. It expresses the change in angular velocity per unit of time quantitatively.
3. The sign of angular acceleration is positive when the body is rotating in the counterclockwise sense and negative when the body is rotating in the clockwise sense.
4. Angular acceleration is used to study the motion of rotating objects such as the wheel, fan, and earth.

Diagram of Angular acceleration is given below:

$\alpha =\frac{∆\omega }{∆t}where\omega isangularvelocity$
