Modern submarines move by using some sort of motor to drive a propellor (called a screw). The big u-boats have nuclear reactors that heat water to make steam, and have steam turbines that drive the screw through a big reduction gear. There are many smaller submarines that use a battery bank and electric motors with little propellors on them to move around.
The buoyancy force on a submerged submarine equals the weight of the water displaced by the submarine. This force acts in the opposite direction to the gravitational force, allowing the submarine to float or sink in the water.
The force of gravity acts downwards on a submarine, causing it to sink. Buoyancy, which is the upward force exerted by a fluid that opposes the weight of an immersed object, acts in the opposite direction, helping to keep the submarine afloat or rise back to the surface when necessary by adjusting the density of the water within its ballast tanks. By managing these forces, submarines can control their depth underwater.
A submarine rotates its turbines in the opposite direction of normal rotation to cause water to be drawn towards the submarine. The force causing the mass to be moved toward the bow of the submarine is counteracted by the force drawing the submarine backwards.

If the weight of the submarine is equal to the upthrust acting on it, the submarine will float. This is due to Archimedes' principle, which states that an object will float when the buoyant force acting on it is equal to the gravitational force pulling it down.

This displacement of water creates an upward force called the buoyant force and acts opposite to gravity, which would pull the ship down. Unlike a ship, a submarine can control its buoyancy, thus allowing it to sink and surface at will.

The USN's submarine force in WWII was called the SILENT SERVICE.

Yes, the buoyant force on a submarine has been reduced to allow it to "stop floating" and submerge.
