# Cars involve Physics to Drive

A car has many different components that work together to make it move, but how does it speed up and accelerate? How does it turn without falling on its side? What makes the tires stay on the ground? Why does wind slow us down or speed us up? Why does weight matter? These are questions that can be answered with physics. When the gas pedal is pushed the fuel is burnt off in the engine and moves the rear/front axel, which rotates the tires and accelerates the vehicle. There is friction between the tires and the ground, which doesn’t allow the tires to “peel out” and move the vehicle forward. There would be less friction if on ice or sand. That is why people put salt or sand on the ground when the road is icy to create more friction. When driving down the highway your tires will heat up which is also due to friction. Another example would be your engine. When the fuel is burnt that adds heat, but also when the pistons are moving at a high rate they generate heat. Wind is also a factor when driving a vehicle. If you were driving west and there was wind out of the south you would feel your vehicle shake and want to go northwest. That’s because the wind has force and friction against your vehicle to push it in the direction it is blowing. A larger vehicle would feel more “push” than a smaller car would. It would have more surface area for the wind to come in contact with making it easier to push over. A cars weight can also be a deciding factor while driving. If a semi
