Force reduction with Cobra SMARTsense

Article no: P6104469

Principle

The students observe the force that needs to be applied when lifting a mass with the aid of a moveable pulley and notice that the force that needs to be applied when using a moveable pulley is less than the force that needs to be applied for lifting the mass straight up. They also notice that this method directly reduces the force that needs to be applied if the pulley that is used is not heavier than the load that needs to be transported. However, the force must be applied over a longer distance.

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
