| A | B |
|---|
| amplitude | maximum displacement from equilibrium |
| period | time to complete one cycle/vibration/oscillation/wave |
| frequency | cycles/vibrations/oscillations/waves per unit time |
| hertz | unit of frequency |
| second | unit of period |
| m/s | unit of wave speed |
| length, acceleration due to gravity | two factors upon which period of a pendulum depends |
| inverse; reciprocal | relationship between frequency and period |
| elastic potential energy | form of energy stored in a stretched or compressed spring |
| N/m | unit of spring constant |
| F elastic = - k x | Hooke's Law |
| mechanical | wave that requires matter through which to move |
| medium | matter through which a mechanical wave is moving |
| wave | the motion of a disturbance |
| mechanical, electromagnetic | the two types of waves |
| wave speed | frequency multiplied by wavelength |
| crest | point of maximum positive displacement from equilbrium |
| trough | point of maximum negative displacement from equilibrium |
| transverse, longitudinal | the two types of mechanical waves |
| compression | highest density position in a longitudinal wave |
| rarefaction | lowest density position in a longitudinal wave |
| wavelength | distance from crest to crest |
| M, mega | 10^6 |
| n, nano | 10^-9 |
| c, centi | 10^-2 |
| tranverse wave | direction of vibrations in the medium is perpendicular to the direction of wave motion |
| longitudinal/compression wave | direction of vibrations in the medium is parallel to the direction of wave motion |
