Lab 9 Data and Observation By Taylor Rhodes and Ryan Oliveira Independent Variables Length Submerged and Density of Cylinder Dependent Variables Buoyancy Force and Weight of Water Dispersed Buoyant Force on an Object More Dense than Water Submerging the Aluminum Cylinder The section of the graph between 60 70 seconds demonstrates large amounts of systemic error due to the table being bumped by one of the other students in the class Calculating the weight of water dispersed in capstone Buoyant Force on an Object Less Dense than Water Calculating the weight of water dispersed in capstone P unknown density of cylinder Pw density of water W unknown Weight of Cylinder F max buoyant force of buoyancy when cylinder is fully submerged 0 997 3 361 10 2 1 1000 2 73 3 1 32 Calculating the Relative Density of Aluminum and Wood Aluminum Mass 361 g Max Buoyant Force 1 32 N Density of Water 0 997 g cm3 Wood Mass 79 g Max Buoyant Force 1 60 N Density of Water 0 997 g cm3 0 997 3 79 10 2 1 1 60 1000 0 492 3 The value we calculated for aluminum is very close to the accepted aluminum density value of 2 72 g cm3 The value we calculated for wood is between the accepted range of wood density values 0 11 g cm 3 1 33 g cm 3 This indicates that our experiment was conducted accurately
