How do objects float on water?
Objects float on water when the weight of the object is less than the weight of the water it displaces. This is due to the buoyant force pushing up on the object. The shape and density of the object also play a role in determining whether it will float or sink.
What is a froce the pulls water up slowing its downward movement?
Surface tension is the force that pulls water up, slowing its downward movement. This force is due to the attraction between water molecules at the water-air interface. It causes water to form droplets and allows objects to float on its surface.
How do objects sink or float in water?
Objects sink or float in water based on their density. If the object is less dense than water, it will float because it weighs less than the water it displaces. If the object is more dense than water, it will sink because it weighs more than the water it displaces. This is due to a balance between the buoyant force pushing up on the object and the gravitational force pulling it down.
What is A force that pulls water up slowing downward motion?
Surface tension is the force that pulls water up, slowing down its downward motion. It is caused by the cohesive forces between water molecules at the surface, creating a sort of "skin" that resists external forces acting on it. This allows small objects to float on the surface of water and for water droplets to form into spheres.
Why do objects that float take out more water than objects that sink?
Objects that float displace more water than objects that sink because the buoyant force acting on the floating object is equal to the weight of the water displaced. This means the weight of the floating object is less than the weight of the water it displaces, causing it to rise and push out more water. Objects that sink do not displace as much water because their weight is greater than the weight of the water they could displace.

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.
How does salt effect an object float in water?
No, salt gets dissolved in water. Fresh water floats above salt water. In places with little mixing (fjords) there can be a several centimeter thick layer of fresh water above the salt water.
Do objects float more easily in salt water or fresh water?
Oh honey, pay attention. Objects float more easily in salt water because salt water is denser than fresh water. It's like trying to float in a kiddie pool versus a hot tub - one is gonna keep you afloat better than the other. So, if you wanna float like a boss, head to the beach and let that salty water do its thing.
Why iron floats on water?
Iron sinks in water because it is denser than water. However, iron is able to float on the surface of water in certain conditions (such as with a carefully placed thin piece of iron) due to surface tension and the water's ability to hold up lighter objects like certain metals.
Why is a buoyant force not present in air?
A buoyant force is not present in air because air is less dense than objects that float in it, so there is no upward force pushing objects up like in water.
Why objects dint float in water?
Objects float (or not) because of their density. In this case, it means that the molecules in it are either packed up really tight, or just loosely holding onto eachother. Water has what is considered an average density. Rocks have a high density. You can tell by holding one, and noting that for how large it is, it is quite heavy. Because of this trait, they sink in water. Some woods, on the other hand, are light as a feather when being even larger than the rock, and because of this, they float on water.
What allows big containers to float in water?
Big containers float in water because their density is less than the density of water. The buoyant force pushing up on the container is greater than the weight of the container pushing down, so it floats. This is based on Archimedes' principle.
