Flotation is the process that allows objects to stay on the surface of a liquid instead of sinking. This occurs when the upward force of the liquid, known as buoyancy, is greater than the weight of the object. Factors like the shape and density of the object, as well as the density of the liquid, play a crucial role in determining whether something will float or sink. In everyday life, we see flotation in action with items like boats and life jackets. These objects are designed to displace enough water to create buoyancy, allowing them to remain on the surface. Understanding flotation is essential in fields like engineering and marine biology.
