Hello everyone,
I'm bit confused about buoyancy. First of all I want to know if it is Newton's third law, filling a vacuum or none of above. For example these are my 3 diffferent understandings of what buoyancy could be. Which one is right
I fall on water and diplace water molecules, do the water molecules give a reaction force back on me calling buoyancy. If that is the case why is it not Newton's third law.
when I displace water molecules, water molecules from underneath come to fill the vacuum and push me up(especially when you displace air isn't this what happens). Is this buoyacny?
Thanks
