Here's why:
* Push or Pull: Centripetal force acts towards the center of the circular path. It can be caused by various forces acting as a push (like a wall pushing a car in a curve) or a pull (like gravity pulling a satellite around the Earth).
* Circular Motion: The key characteristic of centripetal force is that it constantly changes the direction of the object's velocity, keeping it moving in a circle. Without this force, the object would continue in a straight line.
Examples of Centripetal Force:
* A ball on a string: The tension in the string acts as the centripetal force, pulling the ball inwards.
* A car turning: Friction between the tires and the road provides the centripetal force, pushing the car towards the center of the curve.
* A planet orbiting a star: Gravity between the planet and the star acts as the centripetal force, pulling the planet in a circular orbit.
