denser things sink faster the denser it is then the faster it will sink
Not all heavy things sink. Things that are more dense than the liquid around them will sink.
Maybe because they build it to not sink and some things sink because it is how it's made
things that are more dense sink while things that are less dense float
Things that float in a fluid are less dense than the fluid. Things that sink in a fluid are more dense than the fluid.
If density is greater than 1.0 then it will sink in water.
The word "sinkhole" originates from the Middle Low German term "sinken" which means to sink, and "hohl" which means hole. It has been used in English since the 18th century to describe a depression or hole in the ground caused by the collapse of surface layer materials.

things that have higher density than water will sink as a needle but a hip doesnot.
Because of the objects density.
