1. Circular Motion: Forces

2. Centripetal Force All objects that experience circular motion experience a centripetal force.

3. Centripetal Force, pt 2

4. Centrifugal Force From the object’s frame of reference there is an outward force. This is the centrifugal force.

5. Centrifugal Force, pt 2 Force? No, It is Inertia

7. Centripetal Acceleration

8. Centripetal Force

9. r = 0.5 m Ball completes 3 revs in 6 seconds. What is a c ? What is F C ? Uniform Circular Motion m = 1.2 kg

10. Problem #2 A 1500 kg car travels around a circular curve at 35 m/s. The radius of the curve is 150 m. What is the force of friction between the tires and the road required to keep the car from sliding? If the coefficient of friction is 0.90 what is the minimum radius the car could take without slipping?
