No one really "created" buoyancy, the person who founded it was Bernoulli in his principle about fluids. :)
Buoyancy
Positive Buoyancy. When submarine submerges, it initially uses negative buoyancy to submerge, and then levels out to neutral buoyancy.
High buoyancy=easy to float
Yes, all fluids have buoyancy.
yes, it is the same.
We are merely testing the buoyancy of several types of ping pong balls.
The phenomena of buoyancy was first discovered by Archimedes.
buoyancy can be demonstrated if you float something because buoyancy is when something floats for example a boat floating in water
Buoyancy is what keeps a boat floating on the top of the water. Buoyancy is what makes a helium balloon float in the air.
Zero percent buoyancy is actually just sinking. Something that sunk is having zero percent buoyancy
Salt actually increases buoyancy.
The life jacket's buoyancy saved me from drowning.
