Conceptual Physics Alive: Newton's Second Law

Conceptual Physics Alive: Newton's Second 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 2nd Law: The relationship of force, acceleration, and mass is illustrated with a variety of examples. The effects of friction on motion are shown using both sliding and falling objects. Newton's 2nd Law Includes: Hewitt begins with historic evidence against earth at rest. Coin flipping while undergoing accelerated motion. Zero acceleration and zero net force. Newton as a unit of force Demonstration of a block dragged across the table with a force-measuring scale. Questions highlight the concepts of force and acceleration. Airplane thrust and drag. The concept of mass. Comparison of a= (change in v)/t, what acceleration is, and a= F/m, how acceleration is produced. Galilee compared to Newton. Kid skit on falling masses; development of New
