Chapter 11: Harmonic Motion
Term | Definition |
---|---|
Pendulum | a weight hung from a fixed point, so that it can swing freely backwards and forwards |
Cycle | unit of motion that repeats over and over |
Frequency | number of cycles an oscillator makes in one second |
Amplitude | describes how large the cycle is / they depend on the type of oscillation you are describing / it is often distance or angle/ but may be voltage or pressure/ it decreases until the the pendulum stops moving |
Period | the difference between the beginning of the cycle an the end of the cycle |
Oscillator | a system that shows harmonic motion (ex: pendulum, solar system) |
Damping | used to describe the gradual loss of amplitude of an oscillator |
Linear Motion | motion that goes from one place to another (ex: distance, time, speed, etc.) |
Harmonic Motion | motion that repeats itself over and over (ex: pendulum, swing) |
Hertz | unit of frequency |
Phase | where the oscillator is in the cycle |
