This angular acceleration calculator helps to find the acceleration of a rotating body if the moment of inertia and total torque are given.

## What is Angular Acceleration?

According to Wikipedia:

“Angular acceleration refers to the time rate of change of angular velocity.”

In simple words,

“It is the rotation of a rigid body about a fixed center point.”

## Angular acceleration formula

The equation used for the calculation of angular acceleration is:

α = T/I

Where,

α represents angular acceleration,

T represents torque, and

I is moment of inertia.

The formula used in this calculator is related to tangential acceleration as:

αt = αr

Where, αt is tangential acceleration.

## How to find angular acceleration?

Example

Calculate angular acceleration if the body rotates at 30 radians per second and the moment of inertia is 10 kgm2.

Solution:

Step 1: Identify the values.
