1. What is the operational domain?Designed for sustained operation within the underwater environment, distinct from surface-dwelling watercraft
2. What are underwater vehicles and why do we use them?They are machines that travel underwater, letting scientists and workers study the ocean without getting wet. They help us learn about marine life, map the sea floor, and build things like pipelines.
3. How do underwater vehicles stay underwater and come back up?They use ballast tanks that can fill with water to sink or empty with air to rise. This changes the vehicle's density so it can dive or surface.

Hydrodynamics: The study of how fluids (like water) interact with moving objects, influencing vehicle design and movement.
AUV (Autonomous Underwater Vehicle): An uncrewed underwater vehicle that operates independently without a tether, following pre-programmed instructions.
Oceanography: The scientific study of the oceans, including their physical and chemical properties, life, and geological features.
