# Mini-Quiz: Newton's Laws of Motion

by Ron Kurtus (revised 21 May 2014)

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

1. How is inertia used when riding a bicycle?

You must peddle harder when going up hill

You can stop peddling and you will continue rolling forward

Bicycles don't use inertia

2. What happens when you double the force on an object (with no friction)?

You double its acceleration

You cut the acceleration in half

You double its mass

3. If the explosive charge propels a bullet forward with a force of 25 Newtons, what is the force of the recoil of the rifle?

25N + 25N = 50N

25N

25N - 25N = 0

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.
