# Angular Acceleration Calculator

Calculate the angular acceleration of an object. Enter the initial angular velocity, final angular velocity, time and radius to calculate the angular acceleration.

## Angular Acceleration Formula

The formula for calculating the angular acceleration of an object in circular rotation is as follows:

α = (ω₂ – ω₁) / t

• Where α is angular acceleration
• ω₂ – ω₁ is the change in angular velocity
• t is time

Angular acceleration can also be calculated through the following equation:

α = a / R

• Where α is angular acceleration
• a is tangential acceleration
