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
