We can describe the motion of an object if we know the speed it is travelling at, the direction it is moving in and if the speed is changing or staying the same.

In this topic you need to know about the following: -

  • Be able to calculate using the equation distance = speed x time.
  • Suggest speeds of different objects.
  • Convert between m/s and km/h.
  • Explain what acceleration is.
  • Be able to use distance-time and velocity-time graphs.

    • Use the arrows below to continue to revise.
