How can a submarine float and which force is acting on it?
The buoyant force keeps a submarine afloat.
How does something float?
For a certain thing to float, it depends on the mass, weight and the size, . The lighter and smaller a thing is, the more its likely to float. The heavier an object, the more it is likely to stay on the ground. An object can float(or sink) in water, or even in the sky.
What force keeps objects from sinking in water?
Buoyant force.
What force keeps boats floating?
upthrust
How do you float with materials?
To float materials, you need to ensure that the material has a density lower than the fluid it is placed in, like water. This difference in density creates a buoyant force that keeps the material afloat. When the weight of the material is less than the buoyant force acting on it, it will float.
What force keeps your feet on the ground?
Gravity keeps your feet on the ground. It is also what keeps every living and non living thing attached to the earth.
What is up word force on and swimmer the balances the downward force of gravity and keeps the swimmer from sinking?
The force that balances the downward force of gravity on a swimmer is buoyant force. This force is exerted by the water on the swimmer and allows them to float or stay afloat in the water.
Does gravity allow a boat to float on water?
Without gravity, a boat wouldn't be able to float on water, so yes, gravity allows a boat to float (as well as sink into) water. A boat floats from buoyancy force. The buoyancy force is from the volume of water it displaces with it's shape below the water. The buoyancy force is equal to the volume of water it displaces multiplied by 62.4 lbs. per cubic foot (the density of water). So if the boat displaces 20 cubic feet of water with it's hull or shape it can hold 20 x 62.4 = 1248 lbs. of self weight plus cargo. Obviously there should be a factor of safety on that. In summary, a boat needs two things to float on water: Gravity and buoyancy force. Gravity keeps the boat on the water in the first place, but the buoyancy force is the actual thing that keeps the boat afloat. Technically, it is the buoyancy force that allows a boat to float, but if you want to get really technical, it is gravity in the first place that allows a boat to float on water.
How does the property of fluids enable ships and balloons to float?
The property of fluids that enables ships and balloons to float is buoyancy. Buoyancy is the upward force exerted by a fluid that opposes the weight of an object placed in the fluid. This force is greater than the weight of the object, causing it to float. Ships and balloons are designed to displace enough fluid to create a buoyant force that keeps them afloat.
Why buoyancy is called the anti gravity force?
This answer may not be too technical but you will get the general concept. Generally buoyant force is the force which help the objects to float in fluids which includes water and air without sinking. From this its clear that it acts in the direction opposite to the gravity force to make the object float. Gravity is the force that keeps things gown on earth Thus its called the anti gravity force.
What is bouyance?
In physics, buoyancy is the upward force that keeps things afloat. The net upward buoyancy force is equal to the magnitude of the weight of fluid displaced by the body. This force enables the object to float or at least seem lighter.
How does buoyancy float?
Buoancy is the upward force that keeps things floating. I guess it doesn't need surface tension.. http://en.wikipedia.org/wiki/Buoyancy
