![]() ![]() Explain any percent differences which are larger than 10%. Comment on the success of this experiment. Write a conclusion summarizing your results. Compare these two items by calculating the percent difference. Calculate the weight of the displaced fluid. Draw a force diagram for the object in air and in water and show that the buoyant force is the difference between the two weights. Calculate the buoyant force by subtracting the weight of the object under water from the weight of the object in air. Each time dry off the inside of the graduated cylinder. ![]() Repeat the above process for the other three objects. Don’t forget to subtract the mass of the graduated cylinder. In this experiment each lab group will be working. Using the digital scale, measure the mass of the displaced fluid and calculate its weight. The balance reading can be referred to as the apparent mass of the unknown. This is the weight of the object submerged in water. Take the reading of the digital balance and calculate the (apparent) weight of the object. Archimedes principle states that for anybody partially or completely submerged in a fluid is buoyed up by a force equal to the weight of the fluid displaced by. ![]() Continue lowering until the object is completely submerged. This should be done very carefully so as not to spill or splash any water outside. Lower the object into the water while catching the displaced water with a graduated cylinder. Have a container ready to catch the water. Archimedes’ principle, physical law of buoyancy, discovered by the ancient Greek mathematician and inventor Archimedes, stating that any body completely or partially submerged in a fluid ( gas or liquid) at rest is acted upon by an upward, or buoyant, force, the magnitude of which is equal to the weight of the fluid displaced by the body. Fill the beaker with water until the water runs out of the spout. Place the beaker with the spout under the object. Raise the lab jack and hang one of the objects from a hook connected to the bottom of the balance and read the mass of the object and calculate its weight. APPARATUS Triple beam balance, beakers, various objects, supply of water. Archimedes’ principle states that "an object wholly or partially submerged in a fluid experiences a buoyant force upward equal to the weight of the displaced fluid". INTRODUCTION The objective of this experiment is to study Archimedes’ principle by measuring the weights of various objects in air and in water and measuring the weight of the displaced water to see if the data are in agreement with this principle.
