# Average Angular Acceleration Calculator

In an object, the average angular acceleration is defined as the ratio of change in the angular velocity to the time taken by the object to change considering initial and final point of displacement. It is also termed as angular rotational acceleration. It is measured in terms of radians per second squared. Use this online calculator to estimate the average angular acceleration with respect to speed/velocity and time.

#### Formula:

α = Δω / Δt Where, α = Average Angular / Rotational Acceleration Δω = Change in Angular Speed Δt = Change in Time

#### Example

An object with change in angular speed as 23 radians / second and change in time as 11 s will have an average angular acceleration of
α = 23 / 11
α = 2.0909 rad/ s 2
