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
