An airplane is able to move smoothly in the air due to its streamlined aerodynamic design, which reduces air resistance and drag. The wings generate lift, allowing the airplane to overcome gravity and stay airborne. Buoyancy, meanwhile, allows a boat to move smoothly in water. The shape of the boat's hull and displacement of water help it float and navigate with minimal resistance.
Seeing how submarines are designed to move underwater, the antonym that makes the most sense would be airplane.
Fluid friction is defined as occurring between layers within a fluid that are moving relative to each other. It is a resistance so it does not move a submarine through water.
No. A submarine's propeller relies on the water around it for something to push against. As space is a vacuum, the propeller would have nothing to push against, ergo the submarine would have no thrust.
The engines, driving propellers or jets, make the airplane move.
The process of a submarine to move from the surface of the ocean to a position underneath the surface is called a dive. This is accomplished by allowing water to fill the tanks of the submarine, the heavy water pressure now inside the vessel now will force it to sink below the surface, thus a "dive".
A submarine does not have to move under its own power when submerged. It will however move with the water currents that surround it. Just like a hot air balloon moves with the wind (air currents).
That's true for the airplane's wings, when the airplane is flying upright.
A submarine moves forward by using its propeller, which is powered by an electric motor or diesel engine. To move backward, the submarine can reverse the direction of the propeller's rotation or adjust the angle of its hydroplanes to control its depth and direction.
A submarine has neutral buoyancy when its weight is exactly equal to the buoyant force acting on it, causing it to remain suspended at a constant depth without sinking or rising. This balance between weight and buoyant force allows the submarine to move up or down in the water column as needed.
The elevator section of an airplane is located in the aft of the airplane, or on the little wings in the back section of the airplane. The elevators move the airplane on its vertical axis, thereby making the airplane climb or descend.
