Mini-Quiz: Overview of Experiments with Friction

by Ron Kurtus (updated 21 November 2022)

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

1. What effect could the friction factor of materials have on an experiment?

Friction varies with different materials

Some materials will explode when exposed to friction

Materials don't really matter much

2. What is the most important measurement to make in friction experiments?

The elasticity of friction surfaces

The resistive force of friction


3. Why would you want to optimize friction?

To find the best case for your application

To help find the best materials

You really don't want to do that, because friction is bad

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

Friction is needed for things to work
