摘要

The present study employs an interactive approach to understand damped harmonic motion. The insights are provided by the tracker video analysis tool and these videos are analyzed using tracker software to ascertain various physical parameters of the damped harmonic motion. The solutions are derived by making use of a graphical representation of displacement time plot. This method is applied to understand damped harmonic motion in different viscous and non-viscous mediums in terms of the damping coefficient and quality factor. The findings reveal a decrease in damping coefficient with an increase in mass across all mediums. Moreover, it is observed that energy dissipation is higher in water and castor oil with increasing mass, while in contrast, energy dissipation is lower in the air medium, suggesting an undamped nature of motion. Additionally, it is noted that in castor oil, energy dissipation decreases with increasing temperature, indicating a characteristic of under-damped motion.
