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 submarine submerged in the ocean equals what?
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.
How do the forces of gravity and buoyancy affect a submarine?
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.
If a submarine is moving backwards what forse is being caused?
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.
Impulse is the product of force and the what During which that force acts?
time
Will a submarine sink or float when it's weight is equal to the upthrust acting on it?
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.

What are the forces acting on a submarine travelling at a constant depth?
When a submarine is traveling at a constant depth, the primary forces acting on it are buoyancy, gravity, drag (or hydrodynamic resistance), and thrust. The buoyant force, which acts upward, is equal to the weight of the water displaced by the submarine, while gravity pulls the submarine downward. For the submarine to maintain a constant depth, these forces must be balanced, meaning the buoyant force equals the gravitational force. Additionally, the thrust generated by the submarine's engines must counteract the drag force to maintain a steady speed.
How does a submarine change its buoynacy so it can float or sink?
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.
How can a submarine float and which force is acting on it?
The buoyant force keeps a submarine afloat.
When a submarine is underwater does the buoyant force depend on the weight of the submarine?
Yes, the buoyant force acting on a submerged submarine depends on the volume of water displaced by the submarine, not directly on its weight. According to Archimedes' principle, the buoyant force is equal to the weight of the water displaced, which is determined by the submarine's submerged volume. However, for the submarine to be neutrally buoyant and maintain a certain depth, its weight must equal the buoyant force.

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.

Your submarine fleet was known as the?
The USN's submarine force in WWII was called the SILENT SERVICE.
What submarine introduced the all electric drive to the US submarine force?
Virginia class
Has the buoyant force on a diving submarine been reduced?
Yes, the buoyant force on a submarine has been reduced to allow it to "stop floating" and submerge.
