Summary
[edit]DescriptionContainerbrücke (proportional).webm |
Deutsch: Anhand eines Papp-Modelles einer Containerbrücke kann man anschaulich die Rolle der unabhängigen Variablen x und der davon abhängigen Variablen y begreifen.
Die Idee ist es, einen Term T(x) zu finden, mit dem man den dazu passenden y-Wert ausrechnen kann. In diesem Fall ist die Lösung eine proportionale und damit auch eine lineare Funktion der Art y=mx. Der Versuch kann leicht mit billigem Material selbst nachgestellt werden. Eine extrem simple Bauart kann reduziert werden auf ein stabiles Stück Papier, ein Reißzwecke und einen Faden mit zwei Objekten an je einem Ende. Das physikalische Wirkprinzip hinter der Wegverkürzung von x zu y ist der Flaschenzug. English: A very simple cardboard-model of a container bridge helps pupils upwards from age 10 to begin and understand the specific roles of independent and dependent variables. The idea is to find a function or term which maps x to y. In this case, the solution will be a proportional function. The graph will go through the coordinate origin. |
