## Master teacher Paul Hewitt teaches non-computational Conceptual Physics.

Observe Hewitt teach in a classroom with real students, using engaging demonstrations and artwork. Includes all 10 DVD titles; 34 episodes.

#### Conceptual Physics Alive DVD #1

**1. Introduction:**Paul Hewitt talks about teaching physics conceptually and his earlier efforts at videotaping. Short segments of demonstrations done in 1974 and 1984 are shown. We see Paul's opening day lecture at his fall 1989 conceptual physics class at the University of Hawaii, during which Paul poses some thought-provoking questions about the physical world. The introduction is designed to give a flavor of what the Conceptual Physics course is all about. Segment length: 37 minutes

**2. Linear Motion:**Concepts of speed, velocity, and acceleration are introduced and supported with a variety of examples. The effect of air resistance on falling objects is also discussed. Segment length: 33 minutes

**3. Vectors and Projectiles:**Vector addition and vector resolution are explained, using examples such as airplanes flying in the wind and projectile motion. The idea of the independence of the horizontal and vertical components of motion for projectiles is introduced. Segment length: 47 minutes

#### Conceptual Physics Alive DVD #2

**1. 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. Segment length: 45 minutes

**2. 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. Segment length: 42 minutes

**3. Newton's 3rd Law:**The notion that a force is a push or a pull is developed. The concept that forces always occur in pairs as interactions between one thing and another is supported with numerous examples, including a tug-of-war. Segment length: 43 minutes

#### Conceptual Physics Alive DVD #3

**1. Momentum:**Newton's 2nd law is rearranged to the form: Impulse = Change in Momentum. A variety of everyday examples, such as bouncing are used to support this impulse-momentum concept. Conservation of momentum is demonstrated with colliding carts on an air track. Segment length: 50 minutes

**2. Energy:**Mechanical energy in its potential and kinetic forms is illustrated with demonstrations that include a bouncing dart, a pendulum, and a simple pulley system. The conservation of energy is illuminated using everyday examples and a hand-cranked electric generator. Segment length: 48 minutes

**3. Center of Gravity:**The concepts of torque, center of gravity, and center of mass are applied to balancing. Demonstrations include finding the center of gravity of irregularly-shaped objects, a weighted disk that rolls uphill, and a seesaw. Segment length: 33 minutes

**4. Rotation:**The concept of rotational inertia is developed from a variety of everyday examples and demonstrations using weighted objects, and rolling cans filled with both liquids and solids. Finally, Paul stands on a rotating turntable to demonstrate angular momentum. Segment length: 46 minutes

#### Conceptual Physics Alive DVD #4

**1. Gravity I:**The inverse-square law is explained and then related to the law of universal gravitation. Weight and weightlessness, the discoveries of the planets Neptune and Pluto, and the universality of gravitation are also discussed. Segment length: 43 minutes

**2. Gravity II:**The discussion of gravitation continues with the emphasis on ocean, earth, and atmospheric tides. Other topics include tunnels through the earth, black holes, the big bang, and speculations of an oscillating universe. Segment length: 42 minutes

**3. Satellite Motion:**The concept of simple projectile motion is extended to include satellite motion- first circular, and then, elliptical. After a discussion of escape speed, the tape concludes with a summary of previously learned concepts in mechanics. Segment length: 40 minutes

#### Conceptual Physics Alive DVD #5

**1. Special Relativity I:**A discussion on the concept of time dilation leads up to a showing of the 12-minute animated film "Relativistic Time Dilation." Segment length: 49 minutes

**2. Special Relativity II:**Length, momentum, mass, and Einstein's famous equation E=mc2 are discussed and supported with several fanciful examples. Speculations about going faster than the speed of light are entertained. Segment length: 38 minutes

**3. Atoms:**Bohr's atomic model is described, with emphasis on the smallness, emptiness, and plentifulness of atoms. Atomic number, atomic mass, relative atomic sizes, and the wave properties of matter are also discussed. Segment length: 43 minutes

#### Conceptual Physics Alive DVD #6

**1. Scaling:**Surface area and volume are distinguished with simple demonstrations. Several examples are used to illustrate the proportional changes in surface area and volume when objects are scaled up or down in size. Segment length: 39 minutes

**2. Liquids I:**The concepts of density, pressure, and the depth-dependence of liquid pressure are 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

**3. Liquids II:**This tape expands on the discussion of Archimede's principle in the Liquid's I tape, with an emphasis on the law of flotation. A variety of demonstrations help to illustrate these concepts. Segment length: 38 minutes

**4. Gases:**This demonstration-oriented lecture focuses on the atmosphere--its weight, pressure, and the buoyancy it exerts on objects. Barometer, Boyle's Law, and Bernoulli's principle are also discussed. Segment length: 40 minutes

#### Conceptual Physics Alive DVD #7

**1. Heat, Temperature, and Expansion:**Temperature and heat are distinguished from each other. The expansion of solids, liquids, and gases is compared. A discussion on specific heat capacity leads to the physics of a freezing lake. Demonstrations using liquid nitrogen show the effects of low temperatures. Segment length: 44 minutes

**2. Heat Transfer:**Conduction is related to many everyday examples and is demonstrated by boiling water under a variety of conditions. Convection is shown with a pressure cooker. Radiation is related to Newton's law of cooling. Segment length: 45 minutes

**3. Heat Radiation:**The temperature dependence of radiation frequencies are related to the greenhouse effect. The way in which sunlight spreads differently over parts of the earth helps explain the warmth of the equatorial regions and coolness of polar regions. Segment length: 32 minutes

**4. Heat:**Change of State The concepts of evaporation and condensation are contrasted. The energy transfer that accompanies changes of state is related to everyday examples. Segment length: 46 minutes
