Mini-Quiz: Overview of Experiments with Friction

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

   Friction varies with different materialsThat is correct. You are becoming a Champion in experiments. Some materials will explode when exposed to frictionSorry, not correct. Try another button. Materials don't really matter muchGood try, but not right. Select another answer.

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

   The elasticity of friction surfacesSorry, not correct. Try another button. The resistive force of frictionCorrect. You know about friction experiments! LubricationOops! Wrong answer. Re-read the question and try again.

3. Why would you want to optimize friction?

   To find the best case for your applicationThat is correct. You are becoming a Champion in experiments. To help find the best materialsGood try, but not right. Select another answer. You really don't want to do that, because friction is badOops! Wrong answer. Re-read the question and try again.
