Vertical elastic pendulum

With 2 easily interchangeable masses and 2 springs, it allows to demonstrate the influence of mass and the stiffness coefficient k on the natural period of the oscillating system.

A rigid disk can be added to the system to study damping in the air.
The Cinéris software, not provided, allows easy filming and exploitation of all manipulations.

- 1 vise grip for fixing the springs, - 2 springs of different stiffnesses, - 2 weights + rod and color marker: m = 150 and 200 g, - 1 disk for damping: m = 50 g.
