ABSTRACT.
From the perspective of physics, this article analyses the various factors that affect the distance of shot put in the process of actual shot put. Based on the actual situation, it uses fractional calculus and physical formulas to calculate the shot throw distance and conduct a comprehensive analysis. The experiment confirms that the three factors that affect the shot flying distance are the shot angle, shot speed, and shot height, and analyses the relationship between these three factors and the impact of each univariate on the shot flying distance. The analysis results show that three Among the factors, the shot speed has the greatest impact on the flight distance, followed by the shot angle, and the shot height has the least effect; and the optimal shot angle is not a specific value but a general range.

Keywords. fractional differential equation; shot put motion; optimal path; maximum flight distance.
