摘要:

从对物理图像的直观理解角度,利用“运动分解”思想写出了球坐标系中的质点加速度表达式,并通过基于坐标变

换方法和相对运动方法证明该表达式成立.

关键词: 球坐标系, 质点加速度

Abstract:

The expression of particle acceleration in spherical coordinate system is directly written by using the

idea of " motion decomposition" with the consideration of intuitive picture of motion.This expression is proven to be accurate via two different methods:the coordinate transformation and the theory of relative motion.

Key words: spherical coordinates, particle acceleration
