Physics - Unit 6 Test

1. On the test he’s going to ask where the center of gravity / center of mass is. if it’s not moving it’s a vertical line
2. Diagram will be given on the test and you have to label it
3. Zero side of the meter stick is the side without the mass, the 100 side is the side with the mass
4. F${}_1$D${}_1$ = F${}_2$D${}_2$
5. Closed = no mass enters or leaves the system
6. Isolated = no external forces act on the system; no energy enters or leaves the system
