For the same car under the same conditions, the braking distance will increase as your speed goes up. It is primarily affected by the original speed of the vehicle and the coefficient of friction between the tires and the road surface, and negligibly by the tires' rolling resistance and vehicle's air drag. More precise method: Calculate the reaction distance. In fact the braking distance goes up x4 when the velocity goes up x2. s = speed in km/h. Braking distance.

Simple calculations of average speed using the equation: speed = distance/time will be required. r = reaction time in seconds. Example of calculation with a speed of 50 km/h and a reaction time of 1 second: (50 * 1) / 3.6 = 13.9 metres reaction distance. Stopping distance is the total distance needed to bring your vehicle to a complete stop. The average length of a lap is 5 km and the number of laps is usually around 60. Stopping Distance, Thinking Distance, Braking Distance | GCSE Physics - Duration: 2:32. These are compiled from GCSE Physics Specimen Assessment Materials.
