What is the effect of buoyant force on the ability an object has to float?
The buoyant force is what causes and object to float. If the buoyant force is less than the object weight, it sinks. If the buoyant force is greater than the objects weight, it rises to the top. If it is equal, the object will float in the middle, neither rising or falling.
How buoyant force is influenced by gravity?
Buoyant force is entirely the result of gravity. In a gravitational field, we find denser objects sinking in whatever medium they are in (usually air or water) and less dense objects, if the density is lower than the surrounding medium, floating. In the absence of a gravitational field (or in free fall, which is equivalent) everything floats.
Three different liquids and two equal sized cubes are placed in a beaker which of the objects has the greater buoyant force acting on it?
The answer is the beaker on the top because it has less mass
Why do objects have less buoyancy in shallow water?
Shallow water tends to be warmer than off-shore water. Warm water is less dense than colder water so the object would (if its displacement is constant) be less buoyant.
Does the weight of an object immersed in liquid effect the buoyant force on the objects why?
The same object is more buoyant in a denser fluid, and is more likely to float, than in a less dense one. That's why tennis balls float in water but not in air.
Does less ballast makes an object less buoyant?
No, the opposite.
By expanding and contracting their swim bladders fish can change their level in water How does this enable fish to become more or less buoyant?
(a) This helps them become more or less buoyant, because if they release the gas then they will sink making it more buoyant by getting air from the surface or from other bubbles it makes them less buoyant, making them float.
Why do you float better in the sea?
The more salt there is in water the more buoyant an object is. The salt makes the water dense. Objects only float if they have less density than salt.
What objects gives buoyancy?
Buoyancy is linked to density, density being how much material is packed into an object of a certain size. Objects with less density will generally be buoyant in more dense objects.
What is the effect of buoyant force on the ability an object has to float?
The buoyant force is what causes and object to float. If the buoyant force is less than the object weight, it sinks. If the buoyant force is greater than the objects weight, it rises to the top. If it is equal, the object will float in the middle, neither rising or falling.
How can matter be more or less buoyant?
it can be more or less buoyant be having more or less mass.i.e. lead will sink in water because the mass is higher and wood will float because it is lighter. the more mass the less buoyant, less mass means more buoyant.

Why is air more buoyant than water?
Air is more buoyant than water because air is less dense than water, and everything the thing that is less dense is always more buoyant than what is more dense than it.
Is the buoyant force of water on lead greater than that on iron?
That depends on the amounts, of course - what exactly you are comparing. The buoyant force depends on the volume. For a certain volume of lead, there will be the same buoyant force as for the same volume of iron. On the other hand, since lead has a greater density, the buoyant force on a certain amount of MASS of lead will be less, compared to iron, since the same mass of lead will use up less volume.
