This question already has an answer here:
- How does buoyancy work? 5 answers
I would like a detailed explanation and justification if possible regarding the topic. I would like to know what happens at an atomic level. Most of the answers I have found were very basic and did not explain it thoroughly enough. What I have deduced (which does not feel right) is, a denser object has more particles/atoms, therefore, when the object becomes submerged in water it sinks because it exerts more force per area or pressure (because it has more particles to exert the force), that pressure exerted by the object, is stronger than water's (because water is less dense, therefore less pressure) and it sinks, it will only stop sinking at lower depths when the water's pressure increases. Is this similar with why a bullet is able to pierce (not push) through less dense cotton and not denser concrete.
I am a gr.9 student who is enthusiastic about physics and would like to thank in advance for your responses!
