Center of Mass

Question	Answer
What is the center of mass of a system?	Center of mass simplifies systems of objects to treat them as a single point. It is the weighted average of the position of the objects.
How do you estimate the center of mass of 2 unequal mass objects?	The center of mass is always proportionally closer to the heavier object. (2M - - -x- - - - - - M)
When the net external force on a system is zero, the velocity of the center of mass ________________	stays constant (this is a variation of Newton's 2nd law)
__________ forces do not affect the velocity of the center of mass of a system, but _____________ forces do.	Internal . . . net external (Newton's 2nd law variation)
Objects tend to rotate around their _________ __ ______ when no other pivot point is likely.	Center of Mass
