Uniform Circular Motion
Centripetal force, tangential velocity, and motion in a circular plane
Uniform Circular Motion - an object moving at constant speed along a circular path, continuously turned by a center-directed force
“What does this picture tell you about the speed of these motorcyclists?”

“A large centripetal (center directed) force in needed to turn at high speeds.”
The rider needs to lean when they go around a turn at high speeds to counteract the large centripetal force provided by the centripetal force of the tires.
I. Uniform Circular Motion
Why can it be said that the earth has a nearly uniform circular motion around the sun?
The earth moves in a plane around the sun. Define the geometric shape called a plane.
The earth and a motorcycle need something in order to turn. What is that?

In order for an object to move at constant speed in a circle, an outside force must constantly turn the object toward the center of circular path.
