近年来,中国航天事业实现了快速发展,取得了一系列新成就,高考命题也有了这方面的趋势,和圆周运动联系到了一起,圆周运动是一种变速运动,是曲线运其中的一种表现形式,描述圆周运动的物理量有线速度V,角速度ω,周期T,频率f等,而同轴转动具体体现的是角速度相同绕圆心转动的圆周运动,下面从以下几个方面重点论述和其它问题的联系和区别。
In recent years, China’s space industry has achieved rapid development and made a series of new achievements. The college entrance examination proposition also has this trend and is linked with circular motions. Circular motions are a kind of speed-changing movement and one of the manifestations of curve transportation Form, describing the circular movement of the physical speed of the linear velocity V, angular velocity ω, the period T, the frequency f, and coaxial rotation is embodied in the same angular velocity around the center of the circle of circular motion, the following focus from the following discussion and other issues Contact and difference.
