# Mini-Quiz: Static Sliding Friction on an Incline

by Ron Kurtus (22 November 2016)

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

1. How does the normal force vary with the incline angle?

It varies with the cosine of the angle

It is independent of the incline angle

It varies with the cosine of the angle

2. When will the object not slide from the force of gravity?

When the static sliding friction is less than the gravity force down the ramp

The object will always slide a little

When the static sliding friction is greater than the gravity force down the ramp

3. What is an easy way to measure the static coefficient of sliding friction?

Measure the sides at the angle that the object just starts sliding

Measure the time it takes the object to slide down the ramp

There is no easy way to do it

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.

Always try to do your best
