Mini-Quiz: Universal Gravitation Equation

by Ron Kurtus (revised 14 March 2011)

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

1. What was Newton's original equation?

F = Mm/R2

G = Mm/R2

F is proportional to Mm/R2

2. Why was the Cavendish Experiment important?

It determined the value of G

It disproved Newton's equation

It showed that G varies with the mass and separation

3. What is an assumption for the force between large objects?

Both objects are the same size

The mass of each is considered concentrated at is center of mass

The force is infinite

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.
