## Centripetal Acceleration | Definition, Formula, Units – Motion in a Plane

We are giving a detailed and clear sheet on all Physics Notes that are very useful to understand the Basic Physics Concepts.

Centripetal Acceleration Definition:
In circular motion, an acceleration acts on the body, whose direction is always towards the centre of the path. This acceleration is called centripetal acceleration.

Centripetal Acceleration Formula:
Centripetal acceleration, a = $$\frac{v^{2}}{r}$$ = r ω²

Centripetal acceleration is also called radial acceleration as it acts along radius of circle.
Centripetal Acceleration Units:
Its unit is m/s² and it is a vector quantity.

Motion in a Plane (Projectile and Circular Motion):
