Measure of how much distance is passed per time taken.
Equations and Symbols
For constant speeds the gradient of the straight line is equal to the speed.
Speed in a given direction: Two objects moving in opposing directions at the same speed travel at the same , but not with the same .
The change of velocity per unit of time. A negative value of is called .
(with speed changing from to )
Constant acceleration is the gradient of the line relative to the horizontal line at speed .
The distance travelled given acceleration and time can be read from the area of the graph. It's equal to the area!
