Analysis of Curving Ball Based on Mathematical Model

This paper studies curving ball, in perspective of physics and biomechanics, analyzes its forces in the air, describes the curving problems in different situations and makes motion equations. It stresses the deciduous ball, makes its traces in simulated equations and compare with the real situations. We aim at providing references for teaching, training and competition and having a deeper understanding of curving ball. It also supplies more scientific theoretic basis for training teachers and popularizing such technology.
