How does the shape of an object affect its buoyancy?
According to Archimedes's principle:Any object, wholly or partially immersed in a fluid, is buoyed up by a force equal to the weight of the fluid displaced by the object.
So certain shapes will displace more water/fluid and therefore have more force pushing them up. The classic example is an ocean liner which displaces a lot of water so it floats even though it is very heavy. A piece of heavy metal, say a cube, displaces very little water so it sinks. Even a cube of light metal (Aluminum for example) sinks.
A concrete ship, however, can float. A ball floats just as well as a raft, but it's a question of water displacement. A raft displaces the same amount of water as a ball of the same size, but it is spread over a wider area and therefore "sinks" less than a ball would. Also, things with wider bases are less likely to capsize.
Buoyancy is the force a fluid exerts on object. If the density of an object is greater than that of the fluid in which it is placed, it will sink unless it's shape gives it an average density that is less than the fluid, like a boat.
It affects Its Ability To Float By Buoyancy force. The Buoyancy Force Pushes The Object Up While Gravity Pulls The Object Down. The Shape Also Depends Whether The Object Will Float. If Its Flat It Has Possibility To Float .But When The Object Is For Example In a Ball It Will Sink Because It Contains Less Air, And Is Compressed.
The denser the liquid is, the thicker it is, thus making the buoyancy of the object higher.
how does mass affect the shape of an object?
it`s shape,the shape of an object determine the amount of water or air it displaces which enable buoyancy and the shape will also make an object float through friction reduction also.
As we know, the Archimedes' principle tell that for any object in a fluid, the buoyancy force equals to the weight of the fluid displaced by the object. It is pretty straightforward.
Actually, its the mass that affects the buoyancy. Mass controls density, and if an object's mass is more than it's volume, then an object cannot float.
No. Buoyancy depends only on total volume of water displaced and the mass of the object, not the shape of the displacement. However, if the change in the shape affects the volume of water displaced, then the bouyancy of the object is affected. Scuba divers with wet suits know that the volume of their wet suit compresses as their depth increases, causing the suit (and the diver) to become less bouyant.
The denser a liquid, the more buoyancy it provides for an object. You will float higher when swimming in salt water than in fresh water because salt water is denser.
Does the shape of an object affect its volume?
Not at all. (The buoyancy force equals the weight if the displaced water,)
-- Change its mass and weight. Fill any holes inside the object, or carve out new holes inside it. -- Change its volume. Form it into a new shape, like a cup, that displaces much more water than the compact lump does.
buoyancy is a measure of how well an object will float in a given medium, eg: a boat in water. similarly for a blimp, the blimp is the object, the air is the medium. if it is not buoyant enough, it will not 'float' in the air, aka fly
How to calculate centre of buoyancy with diameter 10m .height 100 m and thickness 2inch with density 7850kg per meter cube?
The centre of buoyancy (COB) of an object is the centre of gravity (COG) of the water that is displaced when the object is submerged. So to calculate the COB of an object you first need to calculate the COG of the object and the mass of the object in order to find out how the object will sit in the water and the shape of the water it displaces. Once the shape of the… Read More
The amount of salt in water effects buoyancy (i.e.) the more salt in the water the denser the water the better any object floats in it.
If the average density of an object is less than water (1.0 g per mL) it will float in water, and if it is more than 1.0g/mL it will sink in water. So the lower the density, the greater the buoyancy.
The buoyancy force determines whether or not an object will float. The density of the object in relation to the surface tension of the liquid will affect floating.
In order to float in water, it must have positive buoyancy, so that the amount of water displaced by the object weighs more than the object itself. For example, a boat that weighs 250 lbs but displaces 400 lbs of water will easily float. Buoyancy is an upward force equal to the weight of the water that is displaced. An object that sinks in water has negative buoyancy because the amount of water it displaces… Read More
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.
The shape of an object needs to be such that the overall density of the object is less than that of the medium in which it is placed
The shape of an object affects the wind resistance that will press against the object, slowing it as it falls.
It does not.
An object which is denser than water can float on water when it has a specific shape which lends it buoyancy. For example, a sheet of iron will not float on water but if the same sheet is bent in shape of a bowl, it can float on water.
Water helps lift an objects via the buoyancy force. The buoyancy force is equal to the weight of water displaced by the volume of the submerged object. If this buoyancy force is equal to the weight of the object, the object will float in that position. If the object is completely submerged and the resulting buoyancy force is less than the weight of the object, it will continue to sink.
The shape of an object affects its hydrodynamics. Just like the shape of a wing affects aerodynamics through a medium of air, the shape of an object can vary the affects of drag through a medium of water
If the mass stays the same, then when an object gets larger, its density decreases. The larger density=the more bouyancy

They have no effect on its motion. However they could affect its shape.
If the water displaced by the object in it weighs more than the object itself, the object will have positive buoyancy and float. If the displaced water weighs less than the object in it, the object becomes negatively buoyant and will sink. If the displaced water and the object weigh the same, neutral buoyancy will be achieved, and no change in depth will occur.
This phenomenon is called buoyancy and is caused by the object displacing water equal to its volume. If the weight of the object is less than the weight of this displaced water, then the object has positive buoyancy and will float. If the weight of the object is exactly equal to the weight of this displaced water, then the object has neutral buoyancy and thus be weightless. If the weight of the object is greater… Read More
The higher the density, the lower the buoyancy and the lower the density, the higher the buoyancy
No. But density affects buoyancy.
From Wikipedia: "If the object has exactly the same density as the liquid, then its buoyancy equals its weight. It will tend neither to sink nor float. An object with a higher average density than the fluid has less buoyancy than weight and it will sink. A ship floats because although it is made of steel which is more dense than water, it encloses a volume of air and the resulting shape has an average… Read More
greater density tends to less buoyancy
In air, yes. In vacuum, no.
In air, yes. In vacuum, no.
When there is an object in water, it experiences buoyancy because the water also has weight. The weight of the water pushes the object upwards to make it float.
Non-buoyancy means that an object does not float (I think).
The shape of the object and the density of the gas that the object is falling through.
Fluid density, relative velocity, and object shape affect air resistance.
It has been known since the 16th century that the mass of an object is irrelevant to how far it will fall. The main factor influencing the rate of fall is the shape of the object and, therefore, the air resistance (or buoyancy).
In air, yes. In vacuum, no.
The buoyancy is greater in a salted solution.
Buoyancy is the net upward force experienced by an object in a fluid. Pascal's principle dictates that fluid pressure on an object increases with depth, so there is greater pressure on the bottom of the object than the top, resulting in a net upward force. When an object's buoyancy is greater than its weight, the object will float. An object with neutral buoyancy has a density such that when it is fully submerged the upward… Read More
Buoyancy is the rising of an object through a liquid such as water due to the object being less dense than the liquid. Density is the the mass of an object divided by its volume. Density is often expressed in grams/cm³. For a full explanation of how the buoyancy principle works go to the related question "What is the buoyancy principle?" in the Related Questions section below.
When it has negative buoyancy, it descends (comes down) With positive buoyancy, it ascends (goes up)
Answer yes Wrong. Simply changing the shape of something has no affect on it's weight.
The main factors is the speed, shape and the cross-sectional area of the object.
A force can make a still object move. It can change its shape or size. It can change the way in which it is moving.
Buoyancy is a force exerted by a fluid against an immersed object.
