ArchimedesÕ Principle
¥Archimedes' principle is the law
of buoyancy.
It
states that "any body partially or completely submerged in a
fluid is buoyed up by a force equal to the
weight of the fluid displaced by the body."
¥The weight of an object acts downward, and the buoyant force provided
by the displaced fluid acts upward. If the
density of an object is greater/less than the
density of water, the object will sink/float.
