About Angular Acceleration
Angular acceleration is the rate of change of angular velocity over time. It describes how quickly an object’s rotational speed changes. The SI unit for angular acceleration is radians per second squared (rad/s²).
Key Concepts
- Radians: A unit of angular measure equal to the angle subtended at the center of a circle by an arc equal in length to the radius of the circle (approximately 57.3 degrees)
- Angular Velocity: The rate of change of angular position over time, measured in rad/s, degrees/s, or RPM
- Angular Acceleration: The rate of change of angular velocity, measured in rad/s², degrees/s², or RPM/s
Applications
| Application | Typical Angular Acceleration Range |
|---|---|
| Electric motor startup | 10-100 rad/s² |
| Car engine acceleration | 200-500 rad/s² |
| Hard disk drive spinup | 400-700 rad/s² |
| Industrial centrifuge | 5-50 rad/s² |
| Wind turbine normal operation | 0.1-2 rad/s² |
Note: The relationship between linear and angular acceleration is: linear acceleration = radius × angular acceleration.
