Across
- 5. energy and momentum are conserved
- 6. force times change in time or mass times change in velocity
- 8. change in momentum over change in time
- 10. mass times change in velocity
- 12. of momentum in a closed system with no external forces, the total momentum before is equal to after
Down
- 1. change in momentum
- 2. unit for kinetic energy
- 3. 1/2mass times velocity squared
- 4. kg/N times seconds
- 7. moves at a constant velocity unless an external force acts upon it
- 9. energy is lost and momentum is conserved
- 11. mass times velocity
