People are buoyant in water because of the upward force exerted on them by the water, called buoyant force. This force is equal to the weight of the water the person displaces. People with lower body fat tend to be less buoyant, while objects with greater density than water will sink.

What force makes people float?
The force of buoyancy, which is caused by the difference in the densities of an object and the fluid it is placed in, makes people float. When the buoyant force is greater than the weight of the person, they will float on the surface of the water.
What force makes a rubber duck float in a bathtub?
The buoyant force, which is the upward force exerted by a fluid on an object immersed in it, makes the rubber duck float in a bathtub. The buoyant force is greater than the weight of the duck, causing it to stay afloat.
What makes thing buoyant?
Objects float or are buoyant when the buoyant force acting upward on them is greater than the force of gravity pulling them downward. This is typically achieved when the object is less dense than the fluid it is submerged in, displacing an amount of fluid equal to its own weight. The buoyant force is a result of the pressure difference between the top and bottom of the object, pushing it upwards.
What is the buoyant force acting on a 1000 pound floating in water?
If it's floating, then the buoyant force on it is exactly equal to its weight. (That makes the vector sum of the vertical forces zero, which is why the object is not accelerating vertically.)
What word describes objects that float?
buoyant
What makes the sea so buoyant?
Salt makes sea water more buoyant. The Dead Sea has the most salt of any sea in the world, and even people who cannot swim have no problem floating in it.
What force makes people float?
The force of buoyancy, which is caused by the difference in the densities of an object and the fluid it is placed in, makes people float. When the buoyant force is greater than the weight of the person, they will float on the surface of the water.
Is lead buoyant?
No, lead is not buoyant. It is incredibly dense, which makes it very heavy, and not able to float.
Is it possible for people to swim in the Dead Sea?
Yes, it is possible for people to swim in the Dead Sea due to its high salt content, which makes it extremely buoyant.
What makes it easy to float?
Salt Water, because it is makes things more buoyant.
Does less ballast makes an object less buoyant?
No, the opposite.
Why a lifejacket helps you float?
It's full of air that makes it buoyant
What makes some matter buoyant?
If the object or matter has a density lower than water does.
Why does a beach ball float on water?
Because a beachball is filled with air and that makes it buoyant.
Why are people more buoyant in the Dead Sea?
there is a higher salt content in the dead sea than in the pacific ocean for example.
What force makes a rubber duck float in a bathtub?
The buoyant force, which is the upward force exerted by a fluid on an object immersed in it, makes the rubber duck float in a bathtub. The buoyant force is greater than the weight of the duck, causing it to stay afloat.
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.
