Left to itself an object has a tendency to be at rest or uniform motion in a straight line. Some times we find that some object is moving with a constant speed but changing its direction at a constant rate. Because the speed is not changing there is no acceleration in the tangential direction. But we know that the direction of velocity is changing. So there has to be a force normal to the direction of the speed. it can be proved mathematically that this acceleration is v^2/r. For uniform circular motion This direction happens to be towards the centre of the circle in which the particle moves. This is known as centripetal acceleration. The force which produces this is known as centripetal acceleration. Please note that the centripetal force is not a type of force. It refers to the situation.

An object on which no forces act is eithar standing still or moving at constant speed in a straight line.
The force needed to change that straight-moving motion into a circular motion with constant speed is the centripetal force.
It is always pointing to the center of the circle, and can be calculated as
a = V^2 / r
Where V is the linear speed of the object and r is the radius of the circle.

Centripetal force is a force needed to move in circular motion. Instead of moving in a straight line, it's moving around a circle.

It is the force you need to keep something moving in a circle. A satellite orbiting earth stays in a circular movement because of the pull of gravity from the earth. If you swing a stone at the end of a rope around you, the strength of the rope keeps the stone in a circle

the centripetal force is the force at the center of a circle (well, not a cirlce but when something is in a circular motion.)

its the outward forse caused from spining anything ex. if you spin your arms swing up that is centripetal force
