Angular Acceleration Formula
The following equation is used to calculate the Angular Acceleration.
A = LA / r
- Where A is the Angular Acceleration (rad/s^2)
- LA is the linear acceleration (m/s^2)
- r is the radius (m)
What are the units for Angular Acceleration?
The most common units for Angular Acceleration are rad/s^2.
How to Calculate Angular Acceleration?
The following example problem outlines the steps and information required to calculate the Angular Acceleration.
First, determine the linear acceleration. In this example, the linear acceleration is measured to be 40 (m/s^2).
Next, determine the radius. For this problem, the radius is calculated to be 10 (m).
Finally, calculate the Angular Acceleration using the formula above:
A = LA / r
Inserting the values from above and solving the equation gives us:
A = 40 / 10 = 4 (rad/s^2)
