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!
