Force reduction with a one-sided lever with Cobra SMARTsense

Article no: P6104269

Principle

The students observe the relationship between weight and the length of the lever arm of a one-sided lever and notice that the point of application of different masses affects the effort which is necessary in order to keep the lever in balance. In addition, they see how the force, which needs to be applied, changes depending on the point of application of the dynamometer. They conclude that force (or effort) can be reduced with the aid of a one-sided lever if the mass and dynamometer are positioned in a suitable manner.

Benefits

  • Experiment guides are very easy to understand, especially for younger students
  • Associated competences are directly linked to the experiments
  • Curriculum compatible
  • Fit for the future: implementation of tablets possible
