Work Cited What is buoyancy? Well buoyancy is the ability to float. Have you ever wondered how does a huge ship float in water? A huge ship can float just because of buoyancy. On this page I will explain everything on buoyancy.

** Gravity and the Buoyant Force **

You may be thinking what a buoyant force is. Well a buoyant force is an upward force exerted by a fluid on a submerged object (Jones). Buoyant force goes against gravity, so it makes the object lighter than they really are. If the buoyant force is greater than the weight of the object then it will float to the surface, but If the weight of the object is greater than the buoyant force then it will sink to the bottom. If the buoyant force and the weight of the object is equal then the object won't sink or float.  Archimedes' Principle﻿   ﻿In Archimedes' Principle it states that all object have volume, so it mean it takes up space.It also states that any object submerged in a fluid displaces,or takes the place of, a volume of fluid equal to its own volume(Jones). The water that is displaced is the buoyant force. That's how much buoyant force it is pushing up on the object, just like that picture. The main idea of of Archimedes' Principle is that you can tell how much buoyant force just by weighing the displaced water. ** ToonDoo Examples ** media type="custom" key="7992782" align="center"
