【Abstract】 This paper proposes a new way of determining acceleration of the instantaneous velocity center, that is, when the acceleration of certain one point or two in the plane image has been given, angel acceleration is ascertained, and then the acceleration of the instantaneous velocity center is ascertained. We also discuss the acceleration of the instantaneous velocity center in different situations.更多还原
