Mini-Quiz: Centripetal Force

by Ron Kurtus (revised 11 December 2014)

Take this Mini-Quiz to check your understanding of the lesson material.

1. What can happen if the centripetal force is perpendicular to the direction of motion?

The object can stop moving

You cannot apply a force perpendicular to the line of motion

The object can follow a circular path

2. What is the centripetal force when the Moon travels around the Earth?

There is no centripetal force, since there is no wire or rope connecting them

No one knows for sure

The gravitational force between the Earth and the Moon

3. From the centripetal force equation, happens when the straight-line velocity of an object is doubled?

The centripetal force must be four times as great

The velocity is too fast for centripetal force work

The mass of the object decreases by one-half

If you got all three correct, you are on your way to becoming a Champion in Physics. If you had problems, you had better look over the material again.
