1. Accelerator Pedal: This controls the engine's power output, which in turn determines how fast the car accelerates (increases velocity).
2. Brake Pedal: This applies pressure to the brakes, slowing down the car (decreasing velocity).
3. Steering Wheel: While the steering wheel primarily changes the car's *direction*, it can also indirectly affect velocity. Turning the wheel can cause the car to slow down slightly due to friction and the need to adjust the car's trajectory.
