Enter the tangential velocity and the radius at which an object is rotating into the calculator to determine the centripetal acceleration.

## Centripetal Acceleration Formula

The following equation is used to calculate the centripetal acceleration of an object in rotation/orbit.

a = V^2/r

- Where a is the centripetal acceleration m/s^2
- V is the tangential velocity m/s
- r is the radius m

How to calculate centripetal acceleration

**First, measure the velocity**The key to this step is that the velocity is the tangential velocity. In other words the velocity perpendicular to the radius.

**Next, determine the radius**Either calculate or measure the radius of rotation.

**Finally, calculate the centripetal acceleration**Calculate the centripetal acceleration using the velocity and radius from steps 1 and 2 combined with the formula above.

## FAQ

**What is centripetal acceleration?**

Centripetal acceleration, also known as angular acceleration, is the acceleration acting on an object perpendicular to it’s movement.

**What is tangential velocity?**

Tangential velocity is the velocity of an object tangential to the rotation.
