★ What is Angular acceleration ?​

Answer 1

$\huge\underline{\mathbb\red{❥︎A}\green{N}\mathbb\blue{S}\purple{W}\mathbb\orange{E}\pink{R}}\:$

➡️It is the rate of change of angular velocity with a time of an object in motion. Acceleration is the change in velocity of a moving object with respect to time. If the object moves on a circular direction than its velocity is called angular velocity.

➡️The angular acceleration is also known as rotational acceleration. It is a quantitative expression of the change in angular velocity per unit time. The acceleration vector, magnitude, or length is directly proportional to the rate of change in angular velocity.

Answer 2

The angular acceleration is the time rate of change of the angular velocity and is usually designated by α and expressed in radians per second per second.
