# Mini-Quiz: Gravitation as a Fundamental Force

by Ron Kurtus (revised 22 January 2011)

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

1. How are the strengths of the fundamental forces compared?

The strong nuclear force is designated as 1 and the others are fractions of that force

Each is measured as they compare to gravitation

All fundamental forces have the same strength

2. Which fundamental force has the same range as gravitation?

Strong nuclear force

All of the other forces

Electromagnetism

3. How fast does gravitation travel?

It has infinity speed

The speed of light

9.8 m/s2

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.

Take good care of your health
