Damping Oscillation In Various Medium

For a damped oscillation, energy is lost to overcome the resisting forces i.e. damping forces, such as air resistance, viscosity and friction. In different media, the strength of resisting forces varies, so does the extent of damping.
In the present setup, damping oscillation amplitude with time is recorded for various medium like air, water & other fluids by using rotary motion sensor connected with data logger.

Features:

• Rotary motion sensor with different diameters of pulley (0.025, 0.015, and 0.005 m).
• Data Logger with real time data plotting facility, up to 100K sampling rate.
• Free data analyzing software.
• Series and parallel combination of spring is possible1. Rotary motion sensor with different diameters of pulley (0.025, 0.015, and 0.005 m).

Objectives:

• To investigate the damping effect of air, water, oil or glycerin on an oscillating spring.
• To investigate damping effect by changing spring constant (by connecting spring in series and parallel)
