Because some objects are a lot denser than water so the sink and others are less denser so they float
Whether an object floats or not depends on its density. Density is the amount of mass in a volume, or mass divided by volume. If and object's density is less than that of water, it will float in water, and if an objects density is higher than that of water, it will sink in water. raw material (fishballs will sink down);but it will floats when it is cook. why
Objects float or sink because of their density. An example of an object with low density is a sponge, as it has loads of air bubbles in it, and will float. An example of an object with high density is a brick. This is because the brick doesn't have any air trapped in it, it is "packed in", and is more dense than water, therefore it will sink.
Anything heavier than water sinks; anything lighter than water floats. Or, another way to say it: anything with a higher density than water (water weighs about a gram per cubic centimeter), or a higher specific gravity than water, sinks. If the object weighs less than the weight of water that it displaces, then it floats.
== Yes because the volume of water displaced by a cherry is enough that the buoyant force of the water is able to counteract the force of the cherry's weight.==
Because some objects are a lot denser than water so the sink and others are less denser so they float
Some things float or sink in water due to their density. Objects that are less dense than water will float, while objects that are more dense will sink. This is because the buoyant force acting on an object in water is equal to the weight of the water displaced by the object.
because some objects are much denser(heavier) than water so they sink
Some objects that do not float on water include rocks, metals such as iron and lead, and most types of glass. These items are denser than water, causing them to sink when placed in water.
No, some sink.
Not all small objects float; some small objects are denser than water and will sink. Whether an object floats or sinks depends on its density compared to the density of the liquid it is placed in.
It is to do with to volume and mass.
Objects float in water if they have a density lower than water, while objects sink if they have a density higher than water. Density is a measure of how much mass per unit volume an object has. This is why objects like wood and plastic, which have lower density than water, tend to float, while objects like metal, which have higher density, tend to sink.
Objects float when the weight of the water they displace is greater than their own weight, creating an upward buoyant force. Objects sink when their weight is greater than the buoyant force acting on them, causing them to descend in the water. The density and shape of an object determine whether it will float or sink.
The density of water is called "1.0" Certain objects have a mass greater than 1.0, therefore they will sink. Objects with densities less than 1.0 will float or remain partly submerged.
If the object density is higher than water, it will sink.
Those object which have low density then water like wood, ice etc. can flow and those with high density get sink..
