| Abstract: | As to the conservation of motion of center of mass, the method of absolute coordinate system is generally used in the teaching meterials of theoretic mechanics. But here the author puts forward a new calcutation formula using relative coordinate system and gives examples to compare the using of these two methods, thus shows us the convenience of the method of relative coordinate system |
