Centripetal force

Centripetal force is a force that pulls or pushes things towards the center of a circle when they are moving in a circular path. For example, when you swing around in a circle on a playground swing, there is a force that is keeping you moving in a circular path instead of flinging you off in a straight line.

This force is called the centripetal force, and it usually comes from things like friction, gravity, or tension in a string or rope. The centripetal force keeps objects moving in a circular path by constantly pulling them towards the center of the circle.

Think of it like this: if you tie a string to a rock and twirl the rock around in a circle, the string is pulling the rock inward towards the center of the circle. This force is what keeps the rock moving in a circular path instead of flying off in a straight line.

Centripetal force plays a big role in many things we see every day, from the way cars go around curves on a track to the way planets move in their orbits around the sun. It's a fundamental concept in physics and helps us understand how things move and interact with each other.
