Conceptual Physics Alive: Liquids 2
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 expands on the discussion of Archimede's principle in the Liquid's I video, with an emphasis on the law of flotation. A variety of demonstrations help to illustrate these concepts. Segment length: 38 minutes Liquids 2 Includes: Hewitt begins with review questions about Archimedes' Principle. Demonstration of equal volumes of iron and wood in water. Buoyant force related to volume of water displaced. Demonstration of clay sinking in water, then refashioned like a boat to float. The law of flotation. The role of density on flotation. Variable density of fish. Submarine. Examples of the principle of flotation. Proposed Saturday night project in bathtub. Why a snorkel won't work below 1-meter depth. Life preservers. Distinction between net force and buoyant force. Floating on the Great Salt Lake (or water of high density) Demonstration of a block of wood floating in water, with a series of stimulating questions. Next-Time Question 1: Consider a boat loaded with metal floating in a small container. When the metal is taken from the boat and thrown overboard into the water. Will the level at the side of the container go up, down, or remain the same? Next-Time Question 2: Consider a balloon floating in the water with a suspended weight to make it just barely float. If you push the balloon beneath the surface and let go, will it return to the surface, stay where it is, or sink?
