Center of Mass
Cards in this deck (5)
- 1What 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.
- 2How do you estimate the center of mass of 2 unequal mass objects?The center of mass is always proportionally closer to the heavier object.
