Across
- 2. this is conserved in collisions if the external force is zero
- 5. name of the type of energy recognized by Albert Einstein which said that mass itself is a form of energy
- 8. sum of the kinetic energy and potential energy of the objects in a system
- 11. law of ___; states that in a closed, isolated system, energy cannot be created or destroyed; instead, it is conserved
- 14. the change in kinetic energy
- 16. stored energy due to interactions between objects in a system; formula is mgh
- 17. stored energy due to an object’s change in shape; an example is a spring
- 19. energy of motion; formula is one-half mass times velocity
- 20. the ability of a system to produce a change in itself or the world around it; represented by the symbol E
Down
- 1. energy associated with charged particles
- 3. a collision in which kinetic energy decreases; occurs between soft objects such as ones made of clay
- 4. a collision in which the kinetic energy does not change; occurs between hard objects
- 6. the stored energy due to gravity represented by the symbol GPE
- 7. energy you get from the food you eat
- 9. the position where GPE is defined to be zero
- 10. heat energy; sum of the kinetic energy and potential energy of the particles in a system; symbol is Q
- 12. energy transferred by electromagnetic waves
- 13. energy due to rotational motion; formula is one-half the moment of inertia times the angular velocity
- 15. the unit that energy is measured in
- 18. the energy stored in bonds inside an atom’s nucleus; released when the structure of an atom’s nucleus changes
