In this post, you will find a List of Common circular motions and the sources of centripetal force (in tabular format) for each of these motions.
Any force can be a centripetal force. Centripetal force is an umbrella term given to any force that is acting perpendicular to the motion of an object and thus causing it to go in a circle.
sources of centripetal forces
List of Common circular motions and the sources of centripetal forces:
|Circular Motion||Provider or source of centripetal force|
|Whirling rock on a string||The tension in the string provides the necessary centripetal force|
|An Electron orbiting nucleus of the atom||Centripetal force is provided by the electrical attraction (Coulomb Force) between the electron and the nucleus|
|Car cornering on the road||Centripetal force is sourced by the Friction between tyres and the road|
|The Moon revolving around the Earth||The moon-Earth gravitational attraction provides the centripetal force|
|Artificial Satellite revolving around Earth||The gravitational attraction between the artificial Satellite and the Earth supplies the centripetal force|
Note that this centripetal force is a real force. In all the above examples, you can see that this force is supplied by real forces like gravitational force, electric force, or frictional force.
