# Mini-Quiz: Artificial Gravity Equations

by Ron Kurtus (16 December 2014)

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

1. What linear acceleration would be needed to simulate a weight of 27 kg?

9.8 m/s2

27 m/s2

9.8 m/s

2. What is the equation of centrifugal force as a function of angular velocity?

F = mg

F = mω2r

F = mv2/r

3. As the radius of the spacecraft 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

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
