Mini-Quiz: Gravitational Speed

by Ron Kurtus (revised 22 January 2011)

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

1. Why did Newton decide that the effect of gravitation was instantaneous?

To satisfy Einstein's theories

To satisfy Mercury's orbit

To satisfy Kepler's law

2. How does the curvature of space respond to a change in separation between planets?

The curvature changes according to separation of masses

The curvature causes to planets to stay in one place

The curvature is fixed and does not change

3. How fast do graviton particles move?

They move at the speed of falling bodies

They don't move but remain fixed within a mass

They move at the speed of light

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.
