Whether an object floats or sinks is a function of its relative density, to the medium in which it is placed. If the object is less dense, it floats, If it is more dense, it sinks.
Density = Mass per unit Volume
For an object to float it has to have a density LESSER that water. For an object to sink it must have a density GREATER than water.
Because some objects are a lot denser than water so the sink and others are less denser so they float
because some objects are much denser(heavier) than water so they sink
No, some sink.
It is to do with to volume and mass.
this is the concept that explains why some objects float on water while others sink. it all deals with density.
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.
Any object will float if its density is less than the density of the fluid,and it'll sink if its density is greater than the density of the fluid.
Because of the objects density.
Density : if the weight per "cubic foot" is less than water it floats, if more it sinks.
Maybe because they build it to not sink and some things sink because it is how it's made
Because some objects are heaver than others.
Because air has weight, mass, and density objects will either sink or float in it. Some balloons will float for example.
