Mini-Quiz: Gravitational Escape Velocity Derivation

by Ron Kurtus (revised 19 May 2011)

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

1. At what point is the escape velocity of a rocket determined?

At the altitude that the rocket engine turns off

When the rocket leaves the ground

At the point that KE = PE

2. Why must the final total energy be considered at infinity?

No one is really sure why, except that it works

It is to make the escape velocity much larger

Gravitation hypothetically extends to infinity

3. What law is used to determine the escape velocity equation?

The Law of Conservation of Mass

The Law of Conservation of Energy

Einstein's Law of Relatives

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.
