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