# Mini-Quiz: Centrifugal Force Caused by Inertia

by Ron Kurtus (revised 11 December 2014)

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

1. When swinging an object on a rope, how to you experience the centrifugal force?

You tend to get dizzy

You do not experience the centrifugal force, because it is fictitious

The rope and object provide a force pulling away from you

2. When an object flies off a spinning disk, what direction does it move?

In a straight line, tangent to the disk

In a curved line, the same direction of the disk

It never flies off the disk

3. How does the mass of the object affect its centrifugal force?

Mass has nothing to do with centrifugal force

Centrifugal force decreases as the mass of the object increases

Centrifugal force increases as the mass of the object increases

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.

Some things seem real, but aren't
