The distance time graphs for any object that is
-stationary is a horizontal line
-moving at a constant speed is a straight line that slopes upwards.

-Velocity is speed in a given direction.
-Acceleration is change of velocity per second. Unit for acceleration = m/s2
-Acceleration = change in velocity / time taken

-If a velocity time graph is a horizontal line, the acceleration is zero
-The gradient of the line on a velocity time graph represents acceleration

-The acceleration of an object is given by the gradient of the line on its velocity time graph
-The distance travelled by an object is given by the area under the line of its velocity time graph
