¥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.
