Mini-Quiz: Normal Force in Rolling Friction

by Ron Kurtus (4 October 2016)

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



1. What is the normal force of a wheel on an incline?

The weight of the wheel

The angle of the incline times its cosine

The weight of the wheel times the cosine of the angle

2. What is the normal force on the ground from a wheel and axle on a cart?

The weight of the wheel plus that or the cart

The weight of the axle and the cart

The weight of the wheel minus that of the cart

3. What is the normal force on the top of rollers between two objects?

The weight of the roller

The weight of the top object plus that of the rollers

The weight of the top object

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.
