汽车物理知识（Automotive physics knowledge） I. mechanics 1, the car chassis quality is greater, so that it can reduce the cars center of gravity, increasing the stability of the car when driving. 2. The body of the car is streamlined to reduce the resistance to the car 3. The driving force of the automobile the friction between the driving wheel and the driven wheel in the opposite direction of the friction force of the driving wheel 4, the car in the flat road uniform speed forward - traction and resistance to balance each other, the car by gravity and ground support balance 5. When the car turns the corner: the driver wants to play the steering wheel the force is the cause of changing the movement of the object; the passenger will fall in the opposite direction of the turn because the passengers have inertia 6, the car brakes (deceleration), the driver braking force - change motion of objects; the passengers will be dumped into the garage -- inertial direction; a small force can stop -- with the driver of the lever principle; forced to step on the brake pressure to increase the friction of the brake; when the friction between the wheel and the ground by rolling friction sliding friction 7, there are differences in the size and number of wheels for different types of cars - which are related to the pressure on the road surface 8, the cars seats are designed to be wide and large, so that reduces the pressure on the car, so that people ride comfortable 9, when the car is moving rapidly, the rear of the car will form a low pressure zone, which is the reason why we often see the dust in the tail of the moving car 10, the traffic administrative department of the car driver and front passenger seat belt must be fastened, so it can prevent the harm of inertia; the prohibited overloading of vehicles not only reduce vehicle damage to the pavement, and reduce friction and inertia; the prohibited vehicles speeding - prevent the brakes, the accident caused by distance and reaction th
