Why do some objects float and others dont?
Because some objects are a lot denser than water so the sink and others are less denser so they float
Why things float on water?
Objects will float on water because they aren't as dense as the water itself. A ship will float because there are a lot of compartments filled with air, which is not as dense as water.The above answer is also valid but according to the Archimedes Principle, the buoyant force on a submerged object is equal to the weight of the fluid that is displaced by the object.
How do things float?
things float because they are less denser then the water. second things do not float, the molecules from the water support the molecules from the thing on the water. that is how something heavy can float. it just has to be boyent meaning it is spread out enough so there is more water molecules to hold it up. if you mean in the air it is the same concept.
Can a hockey puck float on water?
No, because a hockey puck has a higher density than water. In some cases, objects with higher density than water can still float on the water, if they are small enough to avoid breaking the surface tension of the water. This is also the case if the object's mass is distributed across a large enough area, so you could float a penny on water if you put it down flat across the water, but it would not float if you dropped it in on its side. You also could not float that penny if you melted it down and made it into a sphere, for example.
Why cork floats in water?
Any object placed in water will be pulled down into the liquid by gravity. But an object less dense than water will only be pulled down until the object displaces an amount of water equal to its own mass. Then it will float. The water will be pushing up equal to the force of gravity pulling down - an equilibrium. Any object that weighs less than its own volume of water will float. It's lower overall density will result in buoyancy.
How do objects float on water?
Items float on water because they are less dense than water that it floats on.
Why object float in water?
Objects float because the air in the object causes it to rise because it is less denser than water. Objects float better in salt water because the salt makes the water more denser helping even heavier objects to float. -Kimberly P.S. I learned all this in 4th grade!!!!!!!!!!!
Do objects float the same in salt water and fresh water?
objects float better because chemicals help make the objects float higher. the more salt the higher the things go
Why objects float or sink when placed on surface of water?
Because of the comparative density. If the objects density is greater than water it will sink, if less then it will float.
Why do some objects float and others dont?
Because some objects are a lot denser than water so the sink and others are less denser so they float
Why does salt water make objects float?
Because it is more dense
What is the difference between an objects that float and the objects thasink in water?
Objects that float in water are less dense than water; while objects that sink in water are more dense than water.
Do objects float better in salt water or tap water?
in salt water you float better because it is hevier than other water they use for maybe pools
Why is it inaccurate to say that all heavy objects will sink in water?
because if the heavy objects have a round bottom they will float
How do objects sink or float in water?
objects with higher density than water sink, ones with a lower density float
What type of objects will float on top of water?
The types of objects that will float on water are foil, most rubber, and some plastic.
Do objects float better in salt water or fresh water?
Objects float better in salt water because the denser the water the easier the object will float for instance if your at a salt water beach you will float easier in a salt water beach then you will floating in a swimming pool.
