- Velocity = speed in a given direction
Speed(m/s)=distance travelled(m) / time taken (secs)
Stationary = horizontal line
The steeper the line the greater the speed of the object
Acceleration (m/s) = change in velocity (m/s) / time taken (s)
To calculate the gradient of the line on a graph, divide the change in the vertical axis by the change in the horizontal axis.
-the gradient of a velocity-time graph represents the acceleration
the area under a velocity-time graph represents the distance covered
