| 851625807 | Distance | size of the gap between two places. length traveled. How far an object has travelled. Distance is a scalar! | |
| 851625808 | Displacement | is the straight line distance from a starting point with direction given. How far away from original spot. How far an object is, and its direction, from the origin. Displacement is a vector! | |
| 851630000 | Average speed | Distance traveled divided by time taken. | |
| 851630001 | Rate | How fast an event happens, e.g. the speed of a reaction | |
| 851630002 | Velocity | A measure of rate of change in position. Unlike speed, it has a direction as well as a magnitude. | |
| 851630003 | Magnitude | Actual brightness of a star | |
| 851630004 | Vector | Any measurement that requires a direction as well as magnitude. | |
| 851630005 | Scalar | Any measurement that only requires magnitude. | |
| 851630006 | Speed | The rate at which a distance is covered. i.e. How fast Average ______ = distance time Measured in km/h or m/s IS A SCALAR! | |
| 851640060 | Distance Time graph | No 'direction' on graph Gradient = average speed | |
| 851640061 | Displacement Time graph | 'Direction' included |
