Analysis of the motion characteristics of the ping-pong ball rocket based on the physical system

Based on classical kinematic theory, this study carried out a thorough quantitative examination of the ping-pong ball rocket’s kinematic behavior. Using Newton’s laws of motion, the study thoroughly investigated how the ping-pong ball’s initial release height, the container’s radius, the container’s coefficient of restitution, and the air resistance coefficient affected the ball’s rebound height. The results indicate that the maximum rebound height of the table tennis ball increases with the initial release height of the container, and does so in an approximately linear manner. The maximum rebound height also increases with the coefficient of restitution of the container, following a trend that is initially gradual and then becomes steep. The maximum rebound height decreases as the base radius of the container increases, with the trend declining sharply at first and then slowly. The maximum rebound height decreases with an increase in the air resistance coefficient, showing an almost linear decreasing trend. Carefully planned experiments were carried out to verify these theoretical conclusions, and Tracker software was used to analyze the results. The reliability of the suggested model is confirmed by the experimental results, which closely match theoretical expectations. The kinematic features of the ping-pong ball rocket are better understood, thanks to this analysis, which also offers a solid framework for the theoretical modeling and experimental validation of related physical systems.
