The Physics of Driving.
I must say, I studied physics at school, and found it extremely boring. Ignorantly be believing that physics will have no real value of my life when I leave school.
I am very sure that I’m not the only one who has thought this, and may continue to feel this way decades on.
That is until we get our licence and start driving or riding. This task can feel routine. We get in, start the car, and head off without thinking too much about what is really happening.
I want to challenge your thinking now to consider this, every time we drive, we are dealing with physics.
Your car is heavy. It is moving fast. And once it is moving, it does not stop, turn, or slow down instantly just because you want it to. That is where the laws of physics come in.
The faster you drive, the harder your car has to work to stop or change direction. At higher speeds, your stopping distance increases, your reaction time matters more, and a small mistake can become much more serious. Catastrophic consequences can be the result.
Friction is what helps your tyres grip the road. Good tyres, dry roads, and sensible speeds give you more control. But rain, gravel, mud, worn tyres, or icy conditions reduce that grip. When grip is reduced, your car is more likely to slide, skid, or lose control.
Corners are another big one. When you take a bend too fast, your car wants to keep moving in a straight line. That is why slowing down before a corner is so important. It gives your tyres a better chance to hold the road and keep the vehicle stable.
Hills also matter. Going downhill, gravity can make your car pick up speed quickly. Going uphill, your car has to work harder. Either way, it pays to stay aware of your speed and avoid rushing.
Sadly, in a crash, physics become brutal. The force of impact rises sharply with speed. A crash at 60 km/h is not just a little worse than a crash at 30 km/h - it can be many times more destructive because the energy involved increases with speed.
Slow down. Leave space. Look ahead. Drive to the conditions.
Safe driving is not just about following road rules. It is about respecting the forces acting on your vehicle every second you are behind the wheel.
Physics does not take a day off.
