| Hint | Answer |
| [A] The basic structure of matter | |
| [B] This temperature marks the point at which the molecules in a substance have enough thermal energy to break various intramolecular bonds; the substance loses a definite volume | |
| [C] An object designed to 'store' energy with two oppositely charged plates positioned in parallel | |
| [D] The effect observed when a frequency emitter is in motion relative to a frequency receptor, therefore shifting the true frequency | |
| [E] Can be transferred between many different varieties, such as kinetic, gravitational potential, and chemical potential, but is always conserved | |
| [F] If the net amount of this vector quantity on a mass is not zero, the mass will accelerate | |
| [G] The fundamental nature of this force is unknown. However, nearly all structures of the universe owe their existence to it, including galaxies, solar systems, and planets | |
| [H] Unit defined mathematically as an inverse second (s^-1 or 1/s) | |
| [I] Known most commonly as an object's resistance to change in velocity | |
| [J] Unit of energy | |
| [K] Scale of temperature, not measured in degrees, that is used in thermodynamics to avoid the negative quantities of other scales | |
| [L] The speed of this wave in a vacuum is thought to be a sort of ultimate, cosmic speed limit | |
| [M] A larger scale manifestation of the electric forces of electrons that results sometimes from an electric current, which can be measured macroscopically | |
| | Hint | Answer |
| [N] A kilogram meter per second squared; a one kilogram mass on the earths surface experiences about 9.8 of these units | |
| [O] The study of how light interacts with matter and the way humans see it (or don't), including lenses and mirrors | |
| [P] A force applied to a specific surface area by a fluid that is caused by molecular collisions with the surface area | |
| [Q] This point particle makes up hadrons, but not leptons or bosons | |
| [R] The measurable efficiency of a mechanism in a circuit exchanging electrical potential energy in a current for other forms of energy | |
| [S] The electromagnetic ________ encompasses all known wavelengths (and their respective frequencies and energies) of light | |
| [T] A force applied away from an objects center of mass, often via a lever arm | |
| [U] This classification of electromagnetic radiation is the cause of sunburns, and is higher energy than visible light | |
| [V] Word used to describe an area or volume that lacks substance and exerts little to no pressure | |
| [W] The product of a force and the distance it acted along; this quantity per unit of time is known as power | |
| [X] This classification of electromagnetic radiation is often used for medical imaging, and is observed by the Chandra Observatory | |
| [Z] A substance with no thermal energy and therefore no atomic or molecular motion has reached absolute ____ | |
