How does a car accelerate?

[DiRachel]

Car accelerates by pressing the accelerator pedal. More information about car acceleration and deceleration is as follows: 1. Accelerator: A control device that regulates engine power (thrust). In piston aircraft engines, the accelerator controls the throttle opening of the carburetor to regulate cylinder filling, thereby determining engine output power. In gas turbine engines, the accelerator controls the metered fuel flow of the fuel regulator, thus determining the thrust generated by the engine. 2. Brake: The action of stopping or reducing the speed of operating locomotives, vehicles, other transportation tools, or machinery. The general principle of braking is to fix a wheel or disc on the high-speed shaft of the machine and install corresponding brake shoes, bands, or discs on the machine base to generate braking torque under external force. The brake device is a mechanical braking device that can slow down the vehicle speed, also known as a decelerator.
