Mini-Quiz: Types of Friction

by Ron Kurtus (9 October 2016)

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



1. What is an example of sliding friction?

Static friction is greater than kinetic friction

Kinetic friction is greater than the static friction

Sliding friction is less than rolling friction

2. What is an advantage of using rollers instead of sliding an object?

Rollers are much less expensive

Rolling friction is much less than sliding friction

Rolling friction has the advantage of being greater than sliding friction

3. Why is it easier to move water through a hose than grease through a hose?

Since grease is slippery, it actually moves easier than water

Water has less viscosity than grease and thus has less fluid friction

Because you would never move grease through a hose in the first place

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.
