This unit includes five programs that cover the following concepts: the inclined plane - demonstrates how an inclined plane allows you to trade increased distance for decreased force; the lever - demonstrates the principle of the lever; mechanical advantage and friction - professors A and B compare the mechanical advantage of an inclined plane with that of a lever; the screw and the wheel - provides examples and definitions of a screw and a wheel; and the pulley - shows how a pulley works to lift a heavy object, and how if you double the number of ropes supporting the weight, you double the mechanical advantage. |
