VERY IMPORTANT NOTES:

  • Gradient=speed
  • Flat sections are where its stopped
  • The steeper the graph, the faster it is going
  • Downhill sections mean its going back towards its starting point
  • Curve represent acceleration or deceleration
  • A steepening curve means its speed up (increasing gradient)
  • A evelling off curve means its slowing down (decreasing gradient)

Calculating Speed from a Distance-Time graph- Its just the gradient

For example: speed=gradient=vertical/horizontal =500/30 = 16.7m/s. Do not forget you have to use the scales of the axes to work out the gradient. Don't measure in cm!
