Eureka! Episode 30 - 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 wavesCollected in Phy.si Videos Feb 8, 2012 -
Eureka! Episode 28 - Heat as Energy
Heat is produced whenever there is movement and friction between two objects. Since movement is a form of energy, it follows that heat must also be a form of energy.Collected in Phy.si Videos Feb 8, 2012 -
Eureka! Episode 4 - Acceleration Part I
With the examples of a bicycle and a baseball player, an important rule of physics becomes apparent. Concept: Force = mass x acceleration.Collected in Phy.si Videos Nov 16, 2011 -
Eureka! Episode 27 - Convection
This program explains how the principle of buoyancy is responsible for the process of heat transfer called convection.Collected in Phy.si Videos Nov 16, 2011 -
Eureka! Episode 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.Collected in Phy.si Videos Nov 16, 2011 -
Eureka! Episode 25 - Volume & Density
This program explains that volume refers to the amount of space an object envelops and that density refers to the amount of mass that is compacted in a given volume.Collected in Phy.si Videos Nov 16, 2011 -
Eureka! Episode 5 - Acceleration Part II
An animated locomotive helps explain how acceleration works and is calculated. The importance of reasonable units is stressed.Collected in Phy.si Videos Nov 16, 2011 -
Eureka! Episode 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.Collected in Phy.si Videos Nov 16, 2011 -
Eureka! Episode 22 - Atoms
This program explains that molecules are made up of atoms. In pure metals, all the atoms are arranged separately in a lattice-work pattern, but in most non-metals, liquids, and gases, the atoms are bunched together intomolecules.Collected in Phy.si Videos Nov 16, 2011 -
Eureka! Episode 21 - Temperature vs. Heat
Eureka! explains that heat refers to quantity of hotness, and is determined by the mass and speed of molecules.Collected in Phy.si Videos Nov 16, 2011 -
Eureka! Episode 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.Collected in Phy.si Videos Nov 16, 2011 -
Eureka! Episode 19 - Expansion and Contraction
Using balloons to illustrate the process, Eureka! shows how, when matter gets hot, its molecules go faster and the solid, liquid, or gas expands.Collected in Phy.si Videos Nov 16, 2011 -
Eureka! Episode 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.Collected in Phy.si Videos Nov 16, 2011 -
Eureka! Episode 17 - Molecules in Liquid
As molecules in a solid get hotter, they vibrate faster and faster and eventually slip out of their lattice-work pattern. When this occurs, the substance melts, changing from a solid to a liquid state.Collected in Phy.si Videos Nov 16, 2011 -
Eureka! Episode 16 - Molecules in Solids
This program defines the three states of matter, and illustrates the lattice-work pattern of molecules in solids. Viewers learn the origin of the word "molecule."Collected in Phy.si Videos Nov 16, 2011 -
Eureka! Episode 15 - The Pulley
Eureka! shows viewers how a pulley works to lift a heavy object.Collected in Phy.si Videos Nov 16, 2011 -
Eureka! Episode 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.Collected in Phy.si Videos Nov 16, 2011 -
Eureka! Episode 13 - Mechanical Advantage and Friction
Professors A and B compare the mechanical advantage of an inclined plane with that of a lever.Collected in Phy.si Videos Nov 16, 2011 -
Eureka! Episode 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."Collected in Phy.si Videos Nov 16, 2011 -
Eureka! Episode 11 - The Inclined Plane
This program demonstrates how an inclined plane allows you to trade increased distance for decreased forceCollected in Phy.si Videos Nov 16, 2011
