Mini-Quiz: Center of Mass Location and Motion

by Ron Kurtus

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

1. How is the relationship for locations of the objects determined?

Be setting location points on the coordinate line

By comparing their masses

By setting the CM to zero

2. How do you determine the velocity of an object from its position?

They are the same items

Velocity is a small change in position with respect to an increment in time

A change in position indicates the velocity is zero

3. Why is the only acceleration due to gravitation?

The motion of the objects compensate for other accelerations

It is a fact that no one understands

Gravitation is the only force acting on the objects

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.
