Puzzle on Work & Energy by Tim Dodson

1. A nuclear reaction in which atomic nuclei of low atomic number fuse to form a heavier nucleus with the release of energy.
3. The movement of energy through substances in longitudinal (compression/rarefaction) waves; form of energy associated with the vibration or disturbance of matter
6. The energy of motion
8. The type of work that occurs when energy is put into a system
9. A special instance of a device that can store elastic potential energy due to either compression or stretching; is said to follow Hooke's Law
11. Expression used for finding gravitational potential energy (hint: 3 variables)
12. The potential energy stored in elastic materials as the result of their stretching or compressing
13. All energy is _____________.
16. The energy stored in an object as the result of its vertical position or height
19. Finish this equation: (.5)(m)(V^2 = ____ [hint: initials]
21. The stored energy of position possessed by an object

1. A nuclear reaction or a radioactive decay process in which the nucleus of a particle splits into smaller parts
2. The standard metric unit of work
4. The standard metric unit of power
5. States that the net work done by forces on a particle causes a change in the kinetic energy of the particle
7. The energy in a substance that can be released by a chemical reaction; stored in the chemical bonds of a substance
10. Part of the energy of an atomic nucleus, which can be released by fusion or fission or radioactive decay
14. The type of work that occurs when energy is taken out of a system
15. The rate at which work is done
17. The minimum amount of energy required to remove an electron from the atom or molecule in the gaseous state
18. The energy a substance or system has related to its temperature (the energy of moving or vibrating molecules)
20. The energy of electromagnetic waves (aka: energy carried by light)
