What force makes people float?
gravity
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.)
This force help a ship float?
The force that helps a ship float is the buoyant force. The buoyant force is exerted by a fluid upwards that opposes the weight of the object immersed.
What makes objects more or less buoyant than other objects?
Their mass (and the density of the fluid they're floating in).
What is the meaning of buoyant?
Buoyant - is something that 'floats' on the surface of whatever medium it is resting on. For example a boat on water is 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?

Is lead buoyant?
No, lead is not buoyant. It is incredibly dense, which makes it very heavy, and not able to float.
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.
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 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 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.)
Why is a person easily carried in water?
Because the air in our lungs and body makes us buoyant (float)
