1. Inertia |
2. Mass
|
3. Speed The concept of speed is introduced to the inertia-mass relationship. Concept: Force varies with mass and rate of change of speed. |
4. Acceleration 1
|
5. Acceleration 2 An animated locomotive helps explain how acceleration works and is calculated. The importance of reasonable units is stressed. Concept: Acceleration = m/s2. |
6. Gravity Isaac Newton's celebrated falling apple is cited to explain the force of gravity and the unit with which the force of gravity is measured. Concept: Force of Gravity = Mass x 10 m/s2. |
7. Weight vs Mass
|
8. Work A circus strongman and a clown help present the physics definition of work. Concept: Work = force x distance. |
9. Kinetic Energy Animated billiard balls help demonstrate kinetic energy-the energy of motion. |
10. Potential Energy
|
11. The Inclined Plane This program demonstrates how an inclined plane allows you to trade increased distance for decreased force. |
12. The Lever Eureka! Demonstrates the principle of the lever; "The longer the arm of the lever to which force is applied, the less that force need be" |
13. Mechanical Advantage and Friction
|
14. The Screw and the Wheel This program provides examples and definitions of a screw and a wheel: a screw is simply a twisted inclined plane, a wheel is simply a circular lever, whose fulcrum has become an axle. |
15. The Pulley Eureka! shows viewers how a pulley works to lift a heavy object. If you double the number of ropes supporting the weight, you double the mechanical advantage. |
16. Molecules in Solids
|
17. Molecules in Liquids A molecules in a solid get hotter, they vibrate faster and faster and eventually slip out of their latticework pattern. When this occurs, the substance melts, changing from a solid to a liquid state. |
18. Evaporation and Condensation A goldfish bowl filled with water demonstrates the process of evaporation in which speeding molecules escape from a liquid to form a gas. |
19. Expansion and Contraction
|
20. Measuring Temperature Eureka! shows viewers how Swedish scientist Anders Celsius invented the Celsius thermometer using the expansion of mercury as a measure of temperature. |
21. Temperature vs Heat Eureka! explains that heat refers to quantity of hotness, and is determined by the mass and speed of molecules. This program demonstrates that a bucket of water at temperature of 50 degrees Celsius contains more heat than a cup of water at 100 degrees Celsius. |
22. Atoms
|
23. Electrons Using an animated model of an atom, Eureka! illustrates how electrons whiz so quickly round the nucleus that they appear to form layers. |
4. Conduction Eureka! looks at the process of conduction, explaining that the application of heat to an object makes the molecules or atoms vibrate faster and cause a short of "domino effect". |
25. Volume and Density
|
26. Buoyancy Showing viewers that objects immersed in a liquid are buoyed up by a force equal to the weight of the liquid displaced, this program explains the principle of buoyancy. |
27. Convection This program explains how the principle of buoyancy is responsible for the process of heat transfer called convection. |
28. Heat as Energy
|
29. Radiation Waves Viewers learn that one of the chief ways in which heat energy moves is in the form of waves. This kind of heat transfer is called radiation. |
30. The Radiation Spectrum Viewers learn that the waves of heat energy radiated by the sun come in many forms which together make a band, or spectrum of energy waves |
