Eureka Physics Videos (New)

This set of videos are out of print but original copyrights to KOCE have been preserved as a set to show how Physics used to be explained to Y7 -> 13 and still should be!


Unit 1: Force and Energy

  1. Inertia
    This program introduces the series and sets forth the concept of inertia, the first law of physics. Things like to keep on doing what they’re already doing.
  2. Mass
    Building on the concept of inertia, Eureka! Adds the factor of mass, tells how it’s measured and show how it differs from size. Concept: Inertia increases with mass.
  3. Speed
  4. Acceleration 1
    With the examples of a bicycle and a baseball player, an important rule of physics becomes apparent. Concept: Force = mass x acceleration.
  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
    Eureka! Explains the difference between weight and mass and shows how only mass is the same on the moon and on the earth.
  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
    A rock teetering on the edge of a cliff is shown to have potential energy-the energy of position.

Unit 2: Simple Machines

  1. The Inclined Plane
    This program demonstrates how an inclined plane allows you to trade increased distance for decreased force.
  2. 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”.
  3. Mechanical Advantage and Friction
    Professors A and B compare the mechanical advantage of an inclined plane with that of a lever.
  4. 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.
  5. 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.

Unit 3: Heat and Temperature

  1. Molecules in Solids
    This program defines the three states of matter, and illustrates the latticework pattern of molecules in solids. Viewers learn the origin of the word “molecule”.
  2. 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.
  3. 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.
  4. Expansion and Contraction
    Using balloons to illustrate the process, Eureka! shows how, when matter gets hot, it’s molecules go faster and the solid, liquid or gas expands. Conversely, when matter gets cold, it’s molecules go slower and the solid, liquid or gas contracts.
  5. Measuring Temperature
    Eureka! shows viewers how Swedish scientist Anders Celsius invented the Celsius thermometer using the expansion of mercury as a measure of temperature.
  6. 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.

Unit 4: The Conduction of Heat

  1. Atoms
    This program explains that molecules are made up of atoms. In pure metals, all the atoms are arranged separately in a latticework patter, but in most nonmetals, liquids, and gases the atoms are bunched together into molecules.
  2. Electrons
    Using an animated model of an atom, Eureka! illustrates how electrons whiz so quickly round the nucleus that they appear to form layers.
  3. 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”.

Unit 5: The Convection of Heat

  1. Volume and 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.
  2. 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.
  3. Convection
  4. 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.
  5. 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.
  6. 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.
