3. What type of acceleration does an object moving with constant speed in a circular path experience?

4. When an object experiences uniform circular motion, the direction of the net force is

5. A car goes around a curve of radius r at a constant speed v. What is the direction of the net force on the car?

6. A car goes around a curve of radius r at a constant speed v. Then it goes around a curve of radius 2r at speed 2v. What is the centripetal force on the car as it goes around the second curve, compared to the first?

7. The centripetal force that causes a car to go round a bend in the road is provided by

8. The centripetal force F acting on a particle of mass m that is travelling with linear speed v along the arc of a circle of radius r is given by

9. Consider a particle moving with constant speed such that its acceleration of constant magnitude is always perpendicular to its velocity.
