Physics - Motion
general terms for Motion
| Term | Definition |
|---|---|
| Frame of Reference | point of view of motion with labeled reference points to allow measurements |
| Position | Location or coordinates |
| Distance | how far |
| Displacement | The change in position with direction |
| Speed | how fast |
| Velocity | how fast in a given direction |
| Acceleration | Rate of change of velocity with respect to time. |
| Instantaneous Speed | speed at a specific moment of time |
| Scalar quantity | quantities that are fully described by a magnitude (or numerical value) alone. (ex. Mass, distance, speed) |
| Vector quantity | quantities that are fully described by both a magnitude and a direction. (ex. Weight, Displacement, velocity) |
| Constant | without changing |
| X-t graph | Graph of position and time. Slope is velocity |
| Motion map | Diagram of position and veclocity arrows that is used to show an objects motion |
| V-t graph | Graph of Velocity vs time. Slope is acceleration. (Area under the curve is displacement.) |
| [m] | the unit used with distance and displacement |
| [m/s] | the unit used with speed and velocity |
| [m/s^2] | the unit used with acceleration |
| [kg] | the unit used with mass |
| [s] | the unit used with time |
