  • Distance time graphs tell you how far something has travelled
  • The gradient (slope) at any point gives you he speed of the object
  • Flat sections are where it’s stopped
  • A steeper graph means it’s going faster
  • Curved represent acceleration
  • A curve getting stealer means it’s speeding up
  • A levelling off curve means it’s slowing down
  • Speed = gradient = verticle/horizontal
  • You can also calculate the average speed of an object over a period of time by dividing the total distance travelled by the time it takes to travel that distance
