Any object that revolves about a single axis undergoes ...

• circular motion

• tangential motion

• centripetal motion

• unifrom tangential motion

When the tangential speed is constant, the motion is described as ...

• uniform tangential speed

• uniform circular motion

• constant circular acceleration

• constant circular motion

If a ferris wheel is moving at a constant speed as it turns, why does each car in the ferris wheel still have an acceleration?

• Because of the change in direction each car undergoes.

• Because a change in speed in each car occurs.

• Because no change in direction takes place.

• Because centripetal acceleration is a vector quantity.

The acceleration directed toward the center of a circular path is called ..
