- Speed is entered in kilometres per hour (km h-1)
- Distance is entres in metres (m)
- Time is entered in seconds (s)
- Deceleration is calculated in metres per second squared (ms-2)
- Deceleration is also presented in terms of the force of gravity (g)
- Calculation will take place automatically when numbers are entered into the Initial speed cell
and one or both of the stopping distance and stopping time cells.
