在高中物理“万有引力定律在天文学上的应用”一节中讨论天体运行规律时是这样处理的 :质量为m的天体 (称环行天体 ) ,环绕质量为M的天体 (称中心天体 ) ,在半径为r的圆周上做匀速圆周运动 ,线速度为v ,角速度为ω ,周期为T ,所需向心力为F向 =m v2r =mrω2 =mr·4π2T2 .质量 In the high school physics “The Application of the Law of Gravity in the Application of Astronomy,” the celestial body’s operation law is dealt with in the following way: a mass with a mass of m (called an orbital celestial body) and a mass with a mass of M around it (called a central celestial body) at a radius To make a uniform circular motion on the circumference of r, the linear velocity is v, the angular velocity is ω, the period is T, and the required centripetal force is F = mv2r = mrω2 = mr·4π2T2.
