  • If a vehicle is travelling at a steady speed, the resultant force on it is zero. The driving forces are equal and opposite to the frictional forces.
  • The faster the speed of a vehicle, the bigger the deceleration needed to stop it in a particular distance. So the bigger the braking force needed.
