Buoyancy!

Today in class we will be adding to our reasons of why things float in fluids (gases and liquids). The buoyant force (bf-our best friend) allows objects to float in fluids. The bf is an upward force that goes in the opposite direction of Weight.


This diagram shows how an object has less weight when put in water. The amount of weight that it loses (the buoyant force) is equal to the weight of the water displaced by the object (Archimede's Priniciple).




Homework: Using the term buoyant force, explain how a boat floats (4-5 sentences).
