Mini-Quiz: Artificial Gravity in Spacecraft

by Ron Kurtus (revised 17 December 2014)

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

1. Why is artificial gravity desirable in a spaceship?

It prevents the spaceship from falling out of space

It is better for the health of an astronaut on a long trip

It allows astronauts to work without space suits

2. As the radius of the donut shape increases, what happen to the rotation speed?

The larger the radius, the slower the necessary rotation

The larger the radius, the faster the station must rotate

There is no relationship between the two

3. Why must the astronaut be fixed to the floor?

So that he does not get dizzy

So that he moves along with the rotation

No one is sure about the reason

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.

Be authentic and not artificial
