| Question | Answer |
|---|---|
| Rate of motion, or rate of change of position | Velocity (v) |
| Rate at which velocity changes | Acceleration (a) |
| Agent that changes motion | Force (F) |
| The amount of energy transferred by a force over a distance | Work (w) |
| Rate of work, or rate at which energy is transferred | Power (P) |
| Force Formula | Mass × Acceleration |
| Work Formula | Force × Distance |
| Power Formula | Work Divided By Time |
| Acceleration Formula | Change in Velocity Divided By Time |
| Velocity Formula | Distance Divided By Time |
| Amount and type of radiation energy absorbed in biologic tissue | Dose Equivalent |
| Amount of radiation energy absorbed in matter | Absorbed Dose |
| Wall behind the bucky or floor (underneath the table) | Primary Barrier |
| All other walls and the ceiling | Secondary Barrier |
| Kilovolt Peak = Electric potential energy = movement of electrons | kVp |
| Milliamperes per second = current | mAs |
| Erwin Schrödinger Created the | Electron cloud Atomic Model (1926) |
| John Dalton Created the | Solid Sphere ("billiard ball") Atomic Model (1803) |
| J.J. Thomson Created the | Plum Pudding Atomic Model, positives and negatives clumped together (1904) |
| Niels Bohr Created the | Solar System Atomic Model (1913) Nucleus with protons and neutrons, and electrons in separate fixed energy |
| Ernest Rutherford Created the | Positive nucleus with negatives circling in ONE orbit, planetary model (1911) |
| Atoms are arranged in rows on the periodic table by their | Atomic Number |
| The closer the orbit is to the nucleus, the________ the binding energy | Higher |
| Binding energy occurs | Due to attraction between orbiting electrons and protons in the nucleus |
| Binding energy- | How tightly the electron is held in its shell; how much energy would be needed to remove the electron from the shell |
| The periodic table of elements was created by | Dmitri Mendeleev in 1869 |
| Same protons (element), different neutrons | Isotope |
| Same neutrons, different protons | Isotone |
| Same atomic mass number (protons + neutrons), different protons (different element) | Isobar |
| Same everything: atomic mass number, protons & neutrons, different energy in nucleus | Isomer |
| The number of protons and neutrons in an atom | Atomic Mass Number |
| The total mass of the combined protons and neutrons | Atomic Mass |
| Atomic Mass is measured in | amu – atomic mass units |
