Conceptual Physics Alive: Newton's First Law

Conceptual Physics Alive: Newton's First Law 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 Newton's 1st Law: The law of inertia and the concept of mass are introduced and supported with a variety of examples and intriguing demonstrations, such as the tablecloth-and-dishes stunt. The concepts of net force and statics are also illustrated. Newton's 1st Law Includes: Hewitt begins by lifting a heavy anvil and discusses the motion the anvil would experience with impressed forces. Historical perspective; Aristotle on motion; cannonballs and arrows. Newton's 1st law; inertia. Blobs of clay are suspended by a coat hanger on Paul's head. How can he see the blob at the back of his head? [By simply turning around; the blobs stay put and demonstrate inertia.] Weight and mass are distinguished. Block of wood (mass) on a piece of cloth is shown. Hew
