An example of centripetal force is a car making a turn on a curve. Other common examples of centripetal force are the planets in the solar system rotating around the sun.
Centripetal force is any accelerated motion in a curved path, which requires a force directed at the center of curvature of the path. Centripetal force means "center seeking" force. When a car makes a turn on a curve, its wheels spin, create friction and generate a force upon the car which is directed toward the center of the curve. The force that causes planets to move around the sun is also directed toward the sun, or the center of the curve.
