Archimedes Principle Lab Name: Poojan Patel Date: 2/23/11 Partners: Fady Alsheikh, Daniel Villamil Purpose: The purpose of this lab is to better understand the principle of buoyancy and to confirm Archimedes principle. Materials: 4 different metals Beaker Water Scale String Data and Results: Metal Weight (Newtons) A 4.89 B 1.95 C 0.54 D 2.85 Metal Density Measured Density Actual Percent error A 10000 11340 11.81 B 2640.82 2698 2.66 C 8201.646 8.75 23.61 D 8521.36 55847 84.74 Conclusion: Archimedes' principle is a law that explains buoyancy or upthrust. It states that when a body is completely or partially immersed in a fluid it experiences an upthrust, or an apparent loss in weight, which is equal to the weight of fluid displaced. An object experiences upthrust due to the fact that the pressure exerted by a fluid on the lower surface of a body being greater than that on the top surface, since pressure increases with

Unformatted text preview: depth. We got accurate numbers for the density of metals A and B. These numbers were very close to actual density. However, we received some unusually high numbers for the percent error for metals C and D. The unusually high numbers might have come from making a wrong measurement prior to getting the density. In order to get the densities that we did we used the formula d= m /v. M is the mass of the object which was measured by using the scale and v is the volume that was displaced when the object was submerged. From this formula we can conclude that the mass is directly proportional to the density and the volume is inversely proportional to the density. If the object were floating the buoyant force would be equal to the weight of the object....
