Buoyant
Buoyancy is the ability to float in fluids.
Gravity is the force of all objects attracted to one.
Friction is the force caused when two objects rub against each other causing them to slow
<span>Archimedes principle explains that the magnitude of that force is proportional to the difference in the pressure between the top and the bottom of the column, and</span> is also equivalent to the weight of the fluid that would otherwise occupy the column, i.e. the displaced fluid.
