The Centripetal Acceleration calculator computes the centripetal accelerationCircular 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").
