A rudder is like the steering wheel of a boat or airplane π’βοΈ. It's a flat, movable piece at the back that helps control direction. Think of it as a fin that guides movement through water or air. Unlike brakes that stop, a rudder guides. It changes the flow, allowing you to turn left or right. A rudder is essential for navigating and maintaining course. Without it, a ship would just drift aimlessly, like a balloon without a stringπ.
