Física para la ciencia y la tecnología (2 volúmenes). Resnick, Robert & Halliday, David (2004).Repeat the process for objects of different masses and shapes and record your data on Table 1.Archimedes principle is a law of physics fundamental to fluid mechanics.It was formulated by Archimedes of Syracuse. Like before, this is the same as the volume of the block since it is totally submerged. Archimedes principle (also spelled Archimedess principle) states that the upward buoyant force that is exerted on a body immersed in a fluid, whether fully or partially, is equal to the weight of the fluid that the body displaces. Use the density equation to find the volume of the displaced water.You now have the mass of the displaced water. Subtract from this value the mass of just the cup that you measured earlier.

With the water still in the catch bucket, measure the mass of the water and bucket together using digital scale.Record the force measurement from the spring scale while the block is submerged. The water that comes out of the spout represents the displaced fluid. Lower the block until it is completely submerged. Record the force measurement from the spring scale before submerging the block into water. Attach the spring scale to the aluminum block.Place the catch bucket back under the overflow can. Dry the catch bucket using the towel on your table. Empty the water from the catch bucket back into the glass beaker. You want the water in the water to be just ready to come out of the hole. Pour water from the beaker into the overflow can until it comes out of the hole. Place the catch bucket under the overflow can exit hole.Measure and record the mass of the catch bucket using a digital scale.Explain how the density plays a key role on flotation of objects. Explain that the buoyant force exerted by fluids arise from the difference in pressure in the submerged object. This can be best explained using the Archimedes principle.Įxplain the differences between solids and fluids. If the density of the object is less than that of the suspending fluid, it will float, if the opposite is true then the object will sink. When you place and object in a fluid it will do one of two things: it will either float or sink. Density is an important quantity because it plays a key role on the floatation of objects. It is generally expressed in units of g/cm3. Where m is the mass of the object and V is the volume. Density is a property of matter and is defined as the ratio of an objects mass to its volume. That is one of the building blocks of the study of movement of matter and it’s used to classify the field in solid and fluids mechanics. However, in a solid the deformation goes on as long as the force is applied, the moment the forces is removed, no more deformation is experienced by the solid.

A fluid is a substance that continually deforms when a force is applied to it and continues to deform even after the force is not applied anymore whereas a solid may or may not deform when a force is applied to it.
