ROTATIONAL MOTION

Does the location of the center of mass depend on the coordinate system used to calculate it?

• Yes
• Only in two dimensions
• No
• Only for asymmetric objects

How many independent components does the angular momentum vector have in three-dimensional space?

• One
• Two
• Three
• Four

Can the center of mass of a system accelerate?

• Never
• Only in a gravitational field
• Yes, if a net external force acts on the system
• Only if the system is rotating

What is a primary advantage of analyzing motion using the center of mass?

• It makes the math harder
• It is only useful for symmetric objects
• It allows the separation of translational and rotational motion
• It eliminates the need for vectors

Is the center of mass reference frame an inertial frame if no external forces act on the system?

• No
• Only if the system is symmetric
• Yes
• Only in deep space
