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.

∙ 12y agoIt depends if its moving, still, accelerating or slowing down.
Moving(to the left):
1) Thrust to the right
2) Viscous drag to the left
3) Upthrust Upwards
4) Gravity/Weight Downwards
Still:
1) Gravity/Weight Downwards
2) Upthrust Upwards
Accelerating:
Same as Moving but with a stronger Thrust
Slowing down:
Same as moving but with a stronger Viscous Drag

How do the forces of gravity and buoyancy affect a submarine?
The force of gravity acts downward on it, and the force of buoyancy acts upward on it. Just like any other object immersed in any other fluid.
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.
The buoyancy force on a submarine submerged in the ocean equals what?
the weight of the water displaced by the submarine.
What is the force that acts against gravity?
The force that acts against gravity is the buoyant force.
How does force cause motion?
An object is stationary until a force acts on it, then when a force acts on it it will keep going the same direction and speed forever, until another force acts on it.
How do the forces of gravity and buoyancy affect a submarine?
The force of gravity acts downward on it, and the force of buoyancy acts upward on it. Just like any other object immersed in any other fluid.
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.

What is the phone number of the Submarine Force Museum in Groton Connecticut?
The phone number of the Submarine Force Museum is: 860-448-0893.
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
The buoyancy force on a submarine submerged in the ocean equals what?
the weight of the water displaced by the submarine.
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.
The buoyancy force on a submarine submerged in the ocean equals?
the weight of the ocean water displaced by the submarine.
What Class submarine introduced the all electric drive to the US submarine force?
Virginia class
