When a vehicle's speed doubles, the vehicle needs about four times the distance to stop. This is due to the kinetic energy of the vehicle, which is proportional to the square of its speed. Therefore, if you double the speed, the kinetic energy increases by a factor of four, necessitating four times the stopping distance.
Because of its energy of motion, when a vehicle’s speed doubles, the vehicle needs about
