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)
