Friction with Cobra SMARTsense

Principle
If a body is pulled over a surface, the force required to pull it is determined by the frictional force. The resulting friction depends on the material and the surface condition.
Benefits

• Especially understandable and didactically prepared description of the experiment (relevance to everyday life, etc.) including protocol questions.
• Future-oriented teaching: Integration into digital science lessons with tablets or smartphones.
• Increased motivation of students by using the intuitive measureAPP.
• Increased media competence.

Tasks

• measure the force required to pull a log across a table. Determine the static and sliding friction for different materials, weight and contact area.

Learning objectives
The students should learn that different frictional forces act depending on the load on a body.
