The force that makes a boat float?

The force that is at work is gravity. If you are thinking of bouyancy, it is not a force.


Why dosent a ship sink?

The bouyancy of the vessel keeps it afloat. As long as the force of bouyancy is larger then the mass of the ship it will stay afloat.


Why a ball of steel sinks but boat made of steel floats?

The steel boat has more bouyancy because it is mostley filled with air as with the steel ball it is dence and heavy so it sinks


How does buoyancy affect whether an object will sink or float?

If you just set the object in the water, the buoyant force never becomes greater than the object's weight. It sinks and sinks, displacing more and more water, building up more and more buoyant force, until the buoyant force is equal to its weight. At that point, the net force on it is zero, it stops sinking, and it stays right there (floating). The only way you can produce a buoyant force greater than its weight is to force it further down and hold it there. Since the buoyant force is greater than its weight, as soon as you let go, the net force on it is up, and it'll rise, partly out of the water until the buoyant force drops to equal its weight, and again ... it'll stay right there. So the answer to the question is: An object can't stay indefinitely in a position where the buoyant force is greater than its weight. If that happens, then it lifts some of itself out of the water, reducing the buoyant force, until the buoyant force is again just equal to its weight.


The force of a fluid that pushes an object up is called?

Buoyant force. It is the upward force exerted by a fluid on an object submerged in it, which acts in the opposite direction to the force of gravity.


What is the force that pushes up on an object in a liquid?

That force is bouyancy. Bouyancy is also present in a gas, but its effects are usually negligible except on objects with very low densities.


As an object sinks deeper into fluid does buoyant force remain the same?

As an object sinks deeper into a fluid, the buoyant force decreases because the amount of fluid displaced by the object decreases. The buoyant force is equal to the weight of the fluid displaced by the object, so as the object sinks, it displaces less fluid and experiences less buoyant force.


Is the upward force on an object called levitation or buoyancy or?

Bouyancy In case of an aircraft or a rocket, it would be called lift.


What is the name given to the force caused by water which keeps boats afloat?
