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. Hewitt asks, 'When yanked, will the block follow the cloth, stay put, or recoil in the opposite direction?' [For humor it follows the cloth, but only because it has been stapled to the cloth!]
  • Demonstration of dishes on a tablecloth, where the cloth is rapidly pulled beneath the dishes.
  • Demo repeated with more massive metal cylinder.
  • Cylinder is rolled across a table, to demonstrate that in the absence of an impressed force a body in motion tends to remain in motion.
  • Concept of net force is explained.
  • Examples illustrate that inertia is a resistance to change.
  • Demonstration of hanging ball and the breaking of strings. This demo compares the role of weight and the role of mass in string breakage.
  • Sledgehammer-and-anvil demo, where Hewitt puts the anvil on his stomach and is hit by the hammer.
  • The example of tightening a hammerhead on a handle illustrates a body in motion tends to remain in motion, which leads to the explanation of why people are shorter at nighttime.
  • Story of Hewitt painting signs with Burl Grey, and how their discussions of physics changed Hewitt's life. Hewitt poses some of the questions asked by Burl.
  • Story of Harry the painter who rearranges the rope support in his bossun's chair, with devastating consequences because of his ignorance of physics.
