The accelerator pedal in a car serves as a control mechanism that allows the driver to increase or decrease the speed of the vehicle. When the driver applies pressure to the accelerator pedal, it sends a signal to the car's engine management system, instructing it to deliver more fuel to the engine. This increased fuel flow results in the engine generating greater power and increasing the RPM (revolutions per minute).

The amount of pressure applied to the accelerator pedal determines the speed at which the car moves. When the driver releases pressure from the accelerator pedal, the fuel flow decreases, and the engine power reduces, leading to a decrease in speed. Essentially, the accelerator pedal is responsible for regulating the supply of fuel and modulating the engine's power output, allowing the driver to control the acceleration and deceleration of the vehicle.
