Pendulum | A swinging lever, weighted at the lower end, for regulating the speed of a clock mechanism |
Cycle | A unit of motion that repeats itself |
Frequency | The number of cycles an oscillator makes per second |
Amplitude | The maximum distance from the average in harmonic motion; Amplitude is often a distance or angle |
Period | The time for one cycle |
Oscillator | A system that shows harmonic motion |
Damping | A decreasing of the amplitude of an electrical or mechanical wave |
Linear Motion | Linear motion is any motion that moves in a straight line in one direction. It can either be in a horizontal, vertical or inclined direction. An object in linear motion will keep the same velocity and direction unless an external force acts against it |
Harmonic Motion | Motion that repeats itself |
Hertz | A unit of one cycle per second used to measure frequency; The abbreviation is Hz |
Phase | Refers to where an oscillator is in its cycle |
