The truck is a very important and versatile vehicle. Ford Motor Company created the first truck in 1925. It was designed to haul waste and transport cargo. For power, trucks use either gasoline diesel fuel. If the truck has a gasoline engine, it uses internal combustion to create power to drive. Inside the engine there are pistons; they compress air mixed with fuel, which ignites and gives your car energy. To control the vehicle's gas consumption, and speed, you step on the gas pedal. This opens up valves, allowing gasoline and air in. In order for the vehicle to stop, they use brakes. Some heavier trucks use breaks on every wheel, and others have breaks connected to the engine. Breaks are used to absorb energy and slow down the vehicle. Most trucks have anti-lock brake systems that stop the wheels from locking, to facilitate braking on slippery surfaces. Trucks also have a suspension system, to prevent the body of the truck from touching the axles. Trucks also have one axle for steering, that may also work as the driving axel. Some trucks have an additional axle. Newton's first law applies to trucks. The vehicle will go the same speed until an outside force is applied to it. The second law applies to them, as well. If a big vehicle hits a smaller one, the smaller one will go farther than if the smaller vehicle hit a big vehicle. Newton's third law applies to vehicles since every action has an equal, and opposite reaction. For example, a truck pushes down the road, while the road uses an equal force and pushes up on the truck's tires. The Law of Gravity affects vehicles, as it enables trucks to drive, stably on the ground. Without gravity, trucks would instead be floating. Truck's rarely surpass a speed of 100mph. A truck has a slow build-up of velocity, and it would take a large amount of ground for it to build up to full speed. If the truck were to crash, it could blow up from being crushed, or just having a minor dent. The inju
