  • The Between Buoyancy And Liquids Of Different Densities

    1513 Words  | 7 Pages

    Our IA demonstrates the relationship between buoyancy and liquids of different densities. As competitive swimmers, we are always striving to find the ideal conditions to swim in. The idea that different densities of liquids could affect the buoyancy of the objects in the liquids immediately sparked an interest to us. What would happen if the pool we swim in was full of rubbing alcohol or vegetable oil instead of water? What would happen to the buoyancy of the objects in the pool? We placed a 200 kg

  • Miniature Hot Air Balloons and Archimedes's Principle of Buoyancy

    922 Words  | 4 Pages

    China as military signaling lanterns (2). Today ethnic Chinese communities celebrate the end of the Lunar New Year Holidays (3) by launching small hot air balloons ( known as Kung-Ming Lanterns ). The first recorded mathematical description of buoyancy (and thus hot air balloon behavior) was developed by Archimedes over 2000 years ago in Greece (4). The bouncy force is summarized by Archimedes's principle , “the magnitude of the buoyant force is always equal the weight of the fluid displaced by

  • How Surface Area Affects the Buoyancy of Wood Essay example

    1095 Words  | 5 Pages

    is in water that allows it to float is called buoyancy. The buoyant force is always equal to the weight of the water displaced by the object in the water. This force was discovered by Archimedes, who was in his bathtub when he wondered why objects seemed lighter when he held them under the water. He found out that if an object is lighter than the weight of the water it displaces, it will float, but if it is heavier, it will sink. The force of buoyancy is important in many different areas, and especially

  • Fluid's Resistance To The Viscosity Of A Fluid

    1744 Words  | 7 Pages

    Viscosity The viscosity of a fluid of measured by said fluid’s resistance to the gradual deformation caused by shear and tensile stress and is identified as a property of a fluid in which opposes the relative motion between two different surfaces of a fluid both moving at different velocities. A fluid that has no resistance to shear stress is known as an inviscid or ideal fluid. Not every fluid is highly or even somewhat viscous though zero viscosity can only be observed at rather lower temperatures

  • The Properties of Hydrostatics

    1903 Words  | 8 Pages

    Three containers are filled with water to the same height and have the same surface area at the base: hence the water pressure and total force on the base of each is the same. Yet the total weight of the water is different for each. Explain this "hydrostatic paradox" The key to this problem is that the force on a container due to the hydrostatic pressure is always perpendicular to the surface of the water. According to Newton’s 3rd law, the container will push back on the water in the exact opposite

  • Physics of Boating Essay

    1133 Words  | 5 Pages

    To keep it simple, let's check out the main thing you should know about a boat: Buoyancy. Buoyancy, by definition, is the upward force exerted by a liquid on any immersed object. If the force of the liquid on the object is greater than that of the object on the liquid then the object will float. In other words buoyancy is dependent upon the density of the liquid and the volume of the object submerged. Buoyancy: Fb= d*g*V Where Fb= the magnitude of the buoyant force d= density of the

  • Physics Of A Simple Wave Simulator

    1941 Words  | 8 Pages

    Physics in the Classroom The activity that I chose, Simple Wave Simulator, covers the ideas of what the properties of a simple wave are. This simulator enables the student to choose whether they want to make a rope wave, simulating a transverse wave, or a longitudinal wave, which simulates a sound wave. The student is also able to change certain properties of the wave, such as frequency, amplitude, and the speed at which the wave is traveling. While using the simulator, students are able to track

    study this principle. For example, it could be tested in any fluid to see if Archimedes’ principle is still correct when dealing with gases; a heterogeneous mixture could replace the water to see demonstrate that it is truly density affecting the buoyancy of the object. This method was used because it required only a simple procedure while still accurately displaying Archimedes’ principle. It also involved taking measurements and using significant figures, which is
