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 |
