According to Archimedes' Principle (which he described in his treatise On Floating Bodies) a body immersed in a fluid experiences a buoyant force equal to the weight of the fluid it displaces. In the case of a floating boat, if the average density of the boat and the air within its hull is less than the density of the water, the mass of the water displaced as it settles into the water will be equal to the to the total mass of the boat but it will displace a volume less than the volume of the boat, thus enough of the boat will remain above the water to allow it to float.
A hollow boat made of plasticine will float because the overall density of the boat is lower than the density of water. The buoyant force acting on the boat is greater than its weight, allowing it to float on the water's surface.
Yes, a paper boat can float on water as long as it is well-made and the paper is not too thin. The boat's ability to float depends on its design and the displacement of water.
It is the displacement of the vessels weight and the freeboard remaining of a vessel that determines whether a vessel will float and or sink. A ship will float higher on salt water (salt water is denser) than if on fresh water (less dense).
The boat floats because the entire boat - including any air contained within - has a total density less than the density of the water.
Boats float because the mass of the water they displace is greater than the mass of the boat. This difference in density creates bouyancy.
Only if the overall density of the boat is less than the medium in which it is placed.
Density is the property that causes a ball to sink and a boat to float. If an object is denser than the liquid it is placed in, it will sink, while if the object is less dense than the liquid, it will float.
A boat floats in water due to the principle of buoyancy, where the weight of the water displaced by the boat is equal to the weight of the boat itself. To help a boat float, it needs a shape that displaces enough water to support its weight. The design of the boat, including its hull shape and materials used, all contribute to its ability to float effectively.
Greater density
The planet Saturn could theoretically float on giant planet like Jupiter because Saturn has a lower density than Jupiter due to its composition being mostly gas and liquid. This would mean that Saturn would have the ability to "float" in the atmosphere of Jupiter, similar to how a boat floats on water.
Indeed yes. Density is defined as mass per unit volume. If all the mass were concentrated in one lump, your boat would no longer float. If the metal walls of the boat were a little thinner, you'd have more boat volume, and lower density.
No gold is more dense than water so it sinks and in the gold rush in Cali they paned underwater
