Newton＇s second law F=ma is a fundamental law of classical mechanics, which have discovered the quantitative relationship between the variation in motion of the object and the extemal force. The particle analyzed a particle whose acceleration not order for zero, in a certain way the article make use of the equilibrium result in dint make problem simplification and get a conclusion to cooperate the projection along the parallel direction in acceleration and the acceleration satisfy Newton the second laws, cooperate in the acceleration direction along the perpendicularity the projection is an equilibrant.
