Definition
| The distance of the oscillating object measured from its equilibrium position |
|
|
Term
|
Definition
| The maximum displacement from the equilibrium position |

Term
|
Definition
| The number of oscillations completed in a second |
|
|
Term
|
Definition
| Unit of frequency. One oscillation in one second |

Definition
|
|
Term
|
Definition
| Two oscillations which are not in step have a phase difference (expressed as an angle). A phase difference of one oscillation is 2π radians. |
|
|
Term
|
Definition
| The force directed towards the centre of the SHM which opposes the displacement at all times. |
|
|
Term
|
Definition
| An oscillation in which the acceleration of a point is proportional to its displacement from equilibrium and is in the opposite direction. |
|
|
Term
|
Definition
| A cyclic disturbance moving away from a source and transferring energy. |
|
|
Term
|
Definition
| A wave that travels through a physical medium by oscillations of the particles. Its energy moves in the direction of the wave, but the particles move in a cycle. |
|
|
Term
|
Definition
| The distance between consecutive points on the wave which are in step (ie in phase) |
|
|
Term
|
Definition
| The speed of travel of the energy of the wave |
|
|
Term
|
Definition
| Wave whose disturbance is perpendicular to the direction of travel of the energy of the wave. |
|
|
Term
|
Definition
| Wave whose disturbance is parallel to the direction of travel of the energy of the wave |
|
|
Term
|
Definition
| The material in which the oscillations of a mechanical wave occur (eg sound in air; ripples on water). Electromagnetic waves require no medium. |
