Mini-Quiz: Fundamental Forces Act at a Distance

by Ron Kurtus

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

1. What happens to the pull of gravitation as you get further from the Sun?

It goes to zero at 1000 km

It decreases as the square of the distance

It stays the same

2. What is the similarity of electrical and magnetic forces?

Opposites attract

They both require and electrical current

They are completely opposite of each other

3. If a strong nuclear force is so strong, how can a Uranium atom split?

The diameter of its nucleus is larger than the range of the strong force

The strong force works with all atoms except Uranium

Explosive neutrons are used to split the atom

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.
