# Centripetal acceleration

From Glossary of Meteorology

## centripetal acceleration

The acceleration on a particle moving in a curved path, directed toward the instantaneous center of curvature of the path, with magnitude

*V*^{2}/R, where*V*is the speed of the particle and*R*the radius of curvature of the path.This acceleration is equal and opposite to the centrifugal force per unit mass.
