Which controls in the car can produce acceleration or deceleration in it?

The accelerator pedal in a car controls acceleration, increasing the speed of the car. When the pedal is pressed, the car accelerates, causing it to move faster. The brake pedal is used for deceleration, slowing the car down. Pressing the brake causes negative acceleration, reducing the car’s speed. Additionally, the clutch in manual cars and gear shifts control the car’s power output, influencing acceleration. By selecting the appropriate gear, the driver can manage the car’s speed and acceleration according to the driving conditions, such as when to speed up or slow down.
