What must be true of any force that produces circular motion?
It must act as a centripetal force, always directed toward the center of the circle to continually change the object’s direction.
What is the magnitude of a centripetal force?
Fc=mv2/r
What is the direction of the centripetal force?
Inward, toward the center of the circular path (whatever direction that happens to be).
How is centripetal acceleration different from other accelerations?
It changes the direction of velocity (points inward), not the speed.
How is centripetal acceleration similar to all other accelerations?
It’s still caused by a net force, and follows a=fnet/m
Can the steering wheel cause acceleration? Why?
Yes. Turning creates centripetal acceleration because friction provides an inward force that changes the car’s direction.
