The **Centripetal Acceleration** calculator computes the centripetal acceleration*Circular Motion* which is the acceleration directed toward the center of a circular motion with constant angular velocity.

**INSTRUCTION:** Choose your preferred units for length and velocity and enter the following:

- (
**r**) - radius of the constant circular motion - |
**v**| - magnitude of the tangential velocity

**Centripetal Acceleration:** The calculator computes the resulting Centripetal Acceleration **(a)** in units of meters per second squared. However, the user can automatically convert this to other acceleration units via the pull-down menu.

Note than if a mass is moving in this circular motion and is affected by this acceleration due to changing angular velocity, that mass will feel a force along the vector direction of `vec(a_"rad")`.
