Mathematical pendulum with COBRA SMARTsense

Principle

A mass, considered as of point form, suspended on a thread and subjected to the force of gravity, is deflected from its position of rest. The period of the oscillation thus produced is measured as a function of the thread length and the angle of deflection.

Benefits

• Quick and easy set-up
• Automatically measure the oscillation period using the light barrier

Tasks

1. For small deflections, the oscillation period is determined as a function of the cord length.
2. The acceleration due to gravity is determined.
3. The oscillation period is determined as a function of the deflection.

Learning objectives

• Duration of oscillation
• Period
• Amplitude
• Harmonic oscillation
