The online centripetal acceleration and force simulations on this page will allow you to know and understand much better how are the forces acting in the circular motion of an object. In particular, you will learn what centripetal acceleration and centripetal force are.
Centripetal acceleration
For a circular motion to occur it is necessary that the moving object has a centripetal acceleration, i.e. an acceleration directed towards the center of the trajectory circumference. It is this centripetal acceleration that continuously modifies the velocity and causes the circular motion. For this centripetal acceleration to exist, it is necessary the existence of a centripetal force that generates the acceleration.
Centripetal force
The centripetal force is the only one strictly necessary for the existence of a circular motion. The centripetal force can be caused, for example, by gravity, as occurs in planetary motion, or, for example, by the tension of a cable as occurs in the spinning motion of a hammer throw. The magnitude of the centripetal force is determined by the mass of the object, its velocity and the radius of the trajectory.
Other forces and accelerations of circular motion
In addition to centripetal force an object in circular motion can be affected by other forces, such as frictional forces, electromagnetic forces, etc. Understanding and analyzing these forces is essential to understand and predict the circular motion of an object in different situations.
