Submarines are just a type of boat or ship that can go under water.
To move they have to have a propeller turned by a motor. There are very rare exceptions.
The motor can be an electric motor powered by batteries, a Diesel or petrol engine burning Hydrogen peroxide and fuel under water (yes seriously) or on some military boats use a nuclear reactor.
The exceptions:The Hunley that was built during the American Civil war was powered by men turning the propeller.There have been some technology demonstrators using the force of going up and down in the water to make the Submarine go forward.
What else can I help you with?
Does fluid friction move a submarine through water?
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.
Can a submarine move itself in space?
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.
How does water pressure affect a submarine?
When a submarine goes farther down in the water, the water pressure becomes greater. If the submarine goes to far, pipes can explode and let in water, or it can implode the submarine
How is pressure used in the control of a submarine's ability to dive?
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".
Can water exert pressure on a submarine?
Yes, water exerts pressure on the hull of the submarine.
When a submarine is submerged but not sitting on the bottom can it simply float in suspense or does it have to keep moving underwater?
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).
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 does water enter the submarine?
Water enters the submarine by letting water out not into its ballast tanks it enters from the flagura to the magura.
A sentence with submarine in it?
A submarine is only used under water.
How does water enter a submarine?
Water enters the submarine by entering through the butthole and leaving from the propellers
What does a submarine alter to rise and fall in water?
A submarine alters its buoyancy to rise and fall in water by adjusting the amount of water in its ballast tanks. When the tanks are filled with water, the submarine becomes heavier and sinks; when air is pumped into the tanks, the submarine becomes lighter and rises. This process allows the submarine to control its depth in the water column effectively.
How do submarines float and sink in water?
a submarine has a water tank. when the tank is filled then submarine sink in the water. and when the tank is empty then submarine float in water. use the formula density= mass / volume as mass increases(when the tank is full of water), the density of the submarine increases and it submerge into the water and vice versa.
