Answer:
THE DYNAMICS OF CIRCULAR MOTION
, is called centripetal force because it is directed all time versus the circle center. Note that it is named only from its direction and not from its physical origin. A force of gravity, friction, electric …or their sum can be in the role of a centripetal force.

A circular motion is defined as a body travelling at a constant speed around the diameter of a circle.
- There are two types of circular motion: uniform and non-uniform.
- It is a uniform circular motion if the tangential component of acceleration is absent, and it is a non-uniform circular motion if the tangential component of acceleration is present.
- The body's basic instinct is to move in a straight path.
- It is compelled to move along the circle when we apply a centripetal force to it.
- The centripetal force is a pseudo-force that acts along the radius and is directed towards the circle's centre.
- According to Newton's first law of motion, the body cannot change its direction of motion and must be propelled in a circular motion by an external force.
- Because this body is constantly changing its direction of motion and experiencing a change in velocity, it experiences acceleration, which is described as radial centripetal acceleration.
- The body has a persistent tendency to revert to its natural linear course as it moves around the circle.
- A centrifugal force is produced by this tendency.
- The centrifugal force is always equal to the centripetal force and opposes it.
