Centripetal Acceleration and Force

Discuss with your neighbor: If you have sunglasses on your dashboard and you go around a corner, what happens to them? Why?

Centripetal Acceleration When a car is going around a corner, it is changing direction and therefore is … accelerating! We call this centripetal acceleration Centripetal - towards the center

More Centripetal Stuff Centripetal Force The force that makes an object accelerate and go in a circle.

Examples of Centripetal Acceleration Going around a curve keys on a string going in a circle Moon going around the earth Force Friction between tires and road Tension in the string Gravity between the two
