Centripetal Acceleration Tutorial

Centripetal Acceleration:

Acceleration directed toward the center of a circular path. This is called as Centripetal(Centrifugal) Acceleration.

Centripetal Acceleration Formula :

Centripetal Acceleration:

Radius:

Velocity:

where,

a = Centripetal Acceleration, r = Circular Radius, v = Velocity,

Centripetal(Centrifugal) Acceleration Example:

Case 1:

A car moving at a speed of 29 m/s moves around a circle with a radius of 20 m. Determine the acceleration of the car. r = 20 m, v = 29 m/s

Step 1:

Substitute the values in the below centripetal acceleration formula:

This example will guide you to calculate the Centripetal Acceleration manually.

Case 2:

A tyre is running around a circle with a radius of 5 m and 12 m/s² of centripetal acceleration. Determine the speed of the tyre. a = 12 m/s², r = 5 m

Step 1:

Substitute the values in the below Velocity formula:

This example will guide you to calculate the velocity manually.
