Sketch a graph of velocity vs. time for the three vehicles using the model that has the motorcycle and car with a constant acceleration until reaching some maximum velocity.

Constant acceleration close accelerationThe rate of change of velocity. It is measured in metres per second squared (m/s²). Acceleration = change of velocity ÷ time taken. is shown by a straight ...

Key fact The gradient of speed-time and velocity-time graphs represent acceleration. The area under a speed-time graph represents the distance travelled.
