Conceptual Physics Alive: Liquids 1

Conceptual Physics Alive: Linear Motion includes a digital video and questions set with answers. Observe Paul Hewitt teach in a classroom with real students, using engaging demonstrations and artwork. In this video, Paul Hewitt teaches the concepts of density, pressure, and the depth-dependence of liquid pressure is used to develop the concept of buoyancy. A variety of demonstrations are used to distinguish between the displacement, volume, weight, and density of immersed objects, and to illustrate Archimede's principle. Segment length: 39 minutes Liquids 1 Includes: The lecture begins with a comparison of the weights and densities of a Styrofoam and lead ball. Density defined. Hewitt places Styrofoam and metal balls in the hands of two students and asks which has the greater weight. Both say the metal. Hewitt demonstrates with a scale that the Styrofoam weighs more. The reason, having to do with pressure is discussed. The force of a book against the table is compared with the pressure of the same book against the table, in different positions. Pressure defined. Equation for liquid pressure is derived. Demonstration of Pascal's vases, wide and narrow. Dam designs are discussed. Examples of blood pressure illustrate liquid pressure. Buoyant force concept is introduced. Demonstration of buoyant force; suspending a metal cylinder in water while weighing it. Demonstration of displacement with an overflow can. Demonstration of Archimedes' principle. Examples to distinguish pressure and buoyancy. Examples of buoyancy with imaginary blocks. Flotation demonstrated. Next-Time Question: Which floats lower in the water, a ship loaded with Styrofoam, or the same ship empty? (SEE RESOURCES TAB FOR A SAMPLE OF QUESTIONS AND CLICK HERE FOR MORE) Please note: The digital content will be sent to the email provided during checkout, once your order has been processed.
