Mini-Quiz: Quantum Theory of Gravitation

by Ron Kurtus (revised 22 January 2011)

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

1. Is a force continuous over extremely small separations?

Yes, as long as you keep applying the force

It depends on the direction of the force

No, the force becomes quantized

2. What is the reason to include gravitation as a fundamental force?

It unifies all the interactions between particles of matter into one concept

It is to avoid arguments between astronomers and physicists

It is a way to explain dark energy and anti-gravitation

3. What is a major problem with the Quantum Theory of Gravitation?

It does not explain how strong gravity is near the Earth

It has been so difficult to verify through experiments

No one really believes 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.

Small things can be deceiving
