Centripetal acceleration measures the change of velocity direction in circular motions. It is calculated by the division between the square of the speed of the moving object and the radius of the circular trajectory. What is centripetal force and centripetal acceleration? Centripetal force appears in ...
Centripetal Accelerationdefines the distance that is covered and the direction of the movement. Since the velocity vector (the direction) of a body changes when moved in a circle - there is an acceleration. a = v2/ r r = v2/ a v = (ar)1/2 Where: a = Centripetal acceleration and is...

The direction of a centripetal force is toward the center of curvature, the same as the direction of centripetal acceleration. According to Newton’s second law of motion, net force is mass times acceleration: Fnet=ma.Fnet=ma. For uniform circular motion, the acceleration is the centripetal ...

Forces due to circular motion and centripetal / centrifugal acceleration. Centripetal and Centrifugal Force are the action-reaction force pair associated with circular motion. Centripetal Acceleration Velocity is a vector - specifying how fast (or slow) a distance is covered and the direction of the...
Force is always in the direction of acceleration, and therefore the force is directed toward the center of the circle. In the above paragraph, we assumed the existence of mass, since all along the discussion has concerned an object spinning around a circle. By definition, an object—that is...
