Since the kinetic energy increases with the square of the speed, an object doubling its speed has four times as much kinetic energy. For example, a car traveling twice as fast as another requires four times as much distance to stop, assuming a constant braking force.
A vehicle's energy of motion is proportional to the square of its increased speed. When the vehicle's speed doubles, it needs about four times the distance to stop. When the vehicle's speed triples, it needs about nine times the distance to stop.riction is critically affected by your brakes, tires, the road surface, and speed. The brakes on your car have to be strong enough to lock the wheels into a skid. Your tires must have enough tread to create good traction. Traction is the friction of gripping power of the tire as it moves on the roadway.
