Abstract: The paper focuses on the deduction of the acceleration formula of any point at the round of pure roll- ing on the fixed surface. The characteristics of tracks of the acceleration instantaneous center at the wheel pure roll- ing on a fixed surface are analyzed, and the movement of the wheels pure rolling is more deeply understood. An ef- fective method of point acceleration of plane motion graphics is provided.

Key words: plane motion, point method, acceleration, instantaneous center of acceleration
