 ACROSS 5. The transfer of energy that result from applying a force over a distance. 7. A quantity that measures the ability to cause change in a physical system. 9. Unit of measure for force. 11. ____ collision: when objects bounce off each other with no loss in the total kinetic energy of the system. 12. A change in momentum created by a force exerted over time. 14. Newton's Third Law: For every ____ force, there is a reaction force equal in strength and opposite in direction. 15. Newton's ____ Law: For every action force, there is a reaction force equal in strength and opposite in direction. 17. Law of ____ of Momentum: If interacting objects in a system are not acted on by outside forces, the total amount of momentum in the system cannot change. 18. Mass multiplied by velocity. DOWN 1. ___ of Conservation of Energy: energy can never be created ar destroyed, just converted from one form into another. 2. ____ collision: when objects change shape or stick together, and the total kinetic energy of a system decreases. 3. If the action is the Earth pulling down on a book, the ____ is the book pulling up on the Earth. 4. The momentum of an object is related to its mass and ____. 6. ____ energy: energy of motion. 8. The ____ of an object is related to its mass only. 10. When two objects hit each other, a(n) ____ occurs. 13. ____ energy: energy due to position. 16. Unit of measure for energy.
