Mini-Quiz: Ramps are Simple Machines

1. What is the purpose of a ramp?

   The friction is usually greatThat is correct. You know about ramps. There are no handles to hold ontoSorry, not correct. Try another button. You are too weak to do the jobGood try, but not right. Select another answer.

2. How does the distance you push the object compare with the height lifted?

   You are going downhillOops! Wrong answer. Re-read the question and try again. You can power the rollersSorry, not correct. Try another button. Friction is much less using rollersCorrect. You are smart!

3. What is a simple way to calculate the mechanical advantage?

   Divide sliding coefficient of friction by rolling coefficientThat is correct. You know about ramps. Divide rolling coefficient of friction by sliding coefficientGood try, but not right. Select another answer. Divide force mechanical advantage by rolling coefficientOops! Wrong answer. Re-read the question and try again.
