1 The tendency or ability of an object to float. BuoyancyThe tendency or ability of an object to float.
2 More than 2,000 years ago, Archimedes discovered the relationship between buoyant force and how much fluid is displaced by an object.Archimedes principle states:The buoyant force acting on an object in a fluid is equal to the weight of the fluid displaced by the object.
3 BuoyancyThe pressure on the bottom of a submerged object is greater than the pressure on the top. The result is a net force in the upward direction.
4 Buoyant ForceThe upward force exerted by a fluid on a submerged or floating object.
5 BuoyancyThe buoyant force works opposite the weight of an object.
6 Archimedes’ principle: Buoyant Force on an object immersed in a liquid equals the weight of the liquid displaced and the weight of the object if it floats.
