![]() ![]() Applications of Floatation: The principles of floatation have many practical applications in everyday life. Understanding the relationship between density and floatation is essential in many fields, including engineering, physics, and chemistry.Ĥ. This is why objects made of materials with a low density, such as wood or cork, float in water, while objects made of materials with a high density, such as iron or lead, sink in water. The density of the object must be less than the density of the fluid it is placed in for it to float. The Importance of Density in Floatation: Density is a crucial factor in floatation because it determines whether an object will float or sink in a fluid. For example, a ship floats because it displaces a volume of water that weighs more than the ship itself.ģ. This means that the weight of the object must be less than the weight of the fluid it displaces in order for it to float. It states that the buoyant force acting on an object submerged in a fluid is equal to the weight of the fluid displaced by the object. The archimedes principle: The Archimedes principle is a fundamental law of physics that explains why objects float or sink in a fluid. For example, a steel ball has a higher density than water, so it sinks, while a plastic ball has a lower density than water and floats.Ģ. Objects with a higher density than the liquid they are placed in will sink, while objects with a lower density will float. The unit of density is typically grams per cubic centimeter (g/cm) or kilograms per cubic meter (kg/m). It is calculated by dividing the mass of an object by its volume. Density is a measure of how much matter is packed into a given volume. Understanding Density: The first step in understanding floatation is to understand density. It is the amount of matter in an object per unit volume, and it is an essential factor that determines whether an object will sink or float in a fluid.ġ. Density is a fundamental property of matter that describes how much mass is packed into a given volume. It is the ability of an object to float on a liquid surface, and it is determined by the density of the object and the liquid.
