What does the salt do? How does it change the way I float and swim and why is it easier.
In: Physics
>Archimedes’ principle states that the upward buoyant force that is exerted on a body immersed in a fluid, whether fully or partially, is equal to the weight of the fluid that the body displaces.
In simpler terms, if you have a 2 liter cube, it’ll float if it weighs less than 2 liters of the water it’s in.
Salt water is heavier than sweet water.
Salt water is denser than fresh water. Since floating is a function of how much water your bodyweight displaces, in a denser fluid you’ll displace less of it for a given weight and thus you’ll float higher and easier.
Sweet water? I’ve never heard this term.
