Basketball field goal percentage has already become the key point in many scholars’ research; this paper carries out deeply analysis of basketball shooting through release angle and release speed two main factors, establishes kinematics model, and analyzes basketball process trajectory. Apply kinematics equation and combine with mathematical knowledge, it deduces general shooting angle range and release speed range. By establishing relative mathematical model and get correlation data, analyzing athlete release speed, angle and height relationships, take these scientific data as references in practical operation, implement targeted training so as to achieve fast improving field goal percentage.
