Braking Distance 101


The braking distance is a concept we drivers know in a practical sense or at least we think we do. But there is science that we can use to really measure how long our cars take to stop after we slam the brakes. In theory, the braking distance or stopping distance (d) in metres equals to initial velocity square (v0^2) divided by coefficient of friction (μ) and gravitational pull of the earth (g). In a mathematical equation it would look like this:


We know nobody likes maths, so we took a shot at making it more relatable and you are welcome to confirm our findings:
⦁ A car travelling at 50km/h (a speed that nobody in Dubai ever drives at) will take a distance of 12.27 metres to come to a complete halt. If you are working out the numbers yourself, remember to convert the speed into metres per second(m/s) simply by dividing it by 3.6. The friction between rubber and cement is 0.8 and gravitational pull as we all know is 9.81 m/s^2.
⦁ Now let us imagine driving on Sheikh Zayed Road, travelling at 110km/h. How long does it take for our car to stop then? Well the answer is 49.15 metres! Which is close to half the length of a football field!
Now, just so you know, we haven’t taken in to account a number of factors that play a part such as, reaction time of the driver, condition of the road, the tyres and the brakes. The latter two cannot be included in the equation but the first two complicate the equation anyway. Want to take a look at the mathematical representation? Here it is:


To conclude, here is the lowdown:
⦁ It will take way longer for you to stop than you think.
⦁ Even if it is somebody else’s fault, you risk your safety and the safety of the passengers and the car when you do not maintain a safe distance from the car in front.
⦁ Tyre and brake maintenance of your car is absolutely critical.
So we invite you to drop in at Splendour Auto Care Center and let us take a look your tyres and brakes. We have a fully equipped facility with specialist technicians and helpful service advisors, eager to ensure your safety.
