Damping with Cobra SMARTsense

Article no: P1003069

Principle
Damping plays a role for every form of vibration. The damping is responsible for the fact that the amplitude of the oscillation becomes smaller with time. Depending on the situation, the damping can be strong or weak.
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

  • Let a spring pendulum swing freely in air and observe the deflection as a function of time. Compare the deflection with the original deflection.
  • Let the mass of the pendulum be immersed in water and observe the deflection as a function of time.

Learning Objectives

The students should observe the vibration amplitudes over longer periods of time and learn about and measure their decrease over time. This leads to the concept of damping, which however is only introduced here qualitatively and not as the usually used logarithmic damping constant.
