Based on methods of principal component analysis, this paper simplifies each indicator that affect basketball team integrated technical score, divides the 17 different indicators that reflectthe integrated technology into five principle components, simply and accurately obtains the overall strength of the basketball team. According to the conclusions shooting percentage and the overall strength have great relevance, so according to the parabolic motion principles in physics this paper builds mathematical model of differential equation for basketball during throwing period, studies several cases when the hit rate is the highest, implements different training programs for different athletes, andimproves the overall strength of the basketball team.
