The aim of this experiment was to investigate the principles of conservation of momentum and energy during collisions, focusing on distinguishing between elastic and inelastic collisions. The study involved analyzing collisional interactions between pucks on a frictionless air table, elucidating fundamental physics laws through practical application.

Two key experiments were conducted involving different collision types. Velocities of the pucks were obtained by analyzing the slopes of graph lines derived from motion tracking during the collisions. For elastic collisions, the velocities before and after impact were measured by tracking puck centers, while for inelastic collisions, velocities at initial contact and post-collision configurations were recorded, including the joint puck velocities and the center positions. These data were then used to compute momentum components using the measured velocities and known puck masses, which were determined from prior calibration. The velocities for each puck in x and y directions were obtained from graphical slopes, ensuring the accuracy of measured parameters.

Results indicated that in elastic collisions, the total momentum was conserved with minor measurement errors, while kinetic energy showed small percentage losses attributable to experimental limitations. The elastic collision’s momentum components before and after impact revealed nearly identical values, confirming conservation laws. Conversely, inelastic collisions displayed significant kinetic energy loss, primarily converting to rotational energy and heat, with momentum components showing close but not perfect conservation due to energy redistribution. These outcomes aligned with theoretical expectations that elastic collisions conserve both energy and momentum, while inelastic collisions conserve momentum but not kinetic energy.

Sources of error in this experiment included air table friction, measurement inaccuracies in velocity determination, and slight misalignments of puck centers. Errors may have also arisen from during the graphical analysis, such as slope estimation inaccuracies. Additionally, unaccounted rotational effects could influence kinetic energy calculations, especially in inelastic collisions where energy is redistributed into rotational modes. External disturbances, vibrations, and calibration errors further contributed to deviations. The precision of measurements was limited by resolution in position tracking and timing, leading to slight discrepancies with theoretical predictions. These factors collectively resulted in small deviations between observed and expected values, emphasizing the importance of meticulous experimental control.

In conclusion, the experiment verified the fundamental laws of conservation of momentum in both elastic and inelastic collisions, although energy conservation was primarily observed in elastic interactions. The results supported the theoretical framework, demonstrating the validity of these physics laws within experimental uncertainties. Overall, the findings confirmed the theoretical principles governing mechanical collisions, reaffirming their applicability in practical scenarios.
