Centripetal acceleration formula an=Fn/m=4π? R/T？ =4π? f？ R=v？ /R=ω？ R=vω.

In the above formula, an stands for centripetal acceleration, Fn stands for centripetal force, m stands for object mass, v stands for linear velocity (tangential velocity) of object circular motion, ω stands for angular velocity of object circular motion, t stands for period of object circular motion, f stands for frequency of object circular motion, and r stands for radius of object circular motion.

According to Newton's second law, the action of force will cause an object to accelerate. The resultant force provides centripetal force, and the acceleration generated by centripetal force is centripetal acceleration. It may be the actual acceleration or the fractional acceleration of the actual acceleration of the object.

The normal acceleration is also called centripetal acceleration. In uniform circular motion, the normal acceleration is constant, and the direction can be determined by the right-hand spiral law.

When a particle moves in a curve, the acceleration along the normal direction of the track is called normal acceleration. Numerically equal to the square of velocity v divided by radius of curvature r, that is, v/r; Or the product of the square of angular velocity and radius r, that is, ω r, its function is only to change the direction of the object's speed, but not the size of the speed.
