知识点三 用割补法求解万有引力的技巧(探究1)
1.有一质量为M 、半径为R 的密度均匀球体,在距离球心O 为2R 的地方有一质量为m
的质点,现在从M 中挖去一半径为R
2的球体,如图1所示,求剩下部分对m 的万有
引力F 为多大?
触类旁通:若上题中被挖去的球体与大球体同圆心,结果如何?
1. 甲、乙两名溜冰运动员m 甲=70kg,m 乙=36 kg ,面对面拉着弹簧秤做圆周运动的溜冰表演(如图1),两人相距0.9 m ,弹簧秤的示数为21 N ,下列判断正确的是( ) A .两人的线速度相同,约为1 m/s B .两人的角速度相同,为1 rad/s C .两人的运动半径相同,为0.45 m D .两人的运动半径不同,甲为0.6 m,乙为0.3 m 知识点四 ★“双星”问题:
两颗质量可以相比的恒星相互绕着旋转的现象,叫双星。
探究1.双星中两颗子星做匀速圆周运动的向心力来源 探究2.双星中两颗子星匀速圆周运动的运动参量的关系 探究3.两子星圆周运动的动力学关系。
设双星的两子星的质量分别为M 1和M 2,相距L ,M 1和M 2的线速度分别为v 1和v 2,角速度分别为ω1和ω2,由万有引力定律和牛顿第二定律得: M 1: 22
121111121
M M v G M M r L r ω==
M 2:
2
2122222222
M M v G M M r L r ω==
在这里要特别注意的是在求两子星间的万有引力时两子星间的距离不能代成了两子星做圆周运动的轨道半径。
4.“双星”问题的分析思路
周期相同: (参考同轴转动问题) T 1=T 2 角速度相同:(参考同轴转动问题)ω1 =ω2 向心力相同:Fn 1=Fn 2

★例题精析
【例1】在天体运动中,将两颗彼此相距较近的行星称为双星。
它们在相互的万有引力作用下间距保持不变,并沿半径不同的同心圆轨道做匀速圆周运动。
如果双星间距为,质量分别为和,试计算:
(1)双星的轨道半径;(2)双星的运行周期;
(3)双星的线速度。
【探究1】(01北京.08宁夏卷)两个星球组成双星,它们在相互之间的万有引力作用下,绕连线上某点做周期相同的匀速圆周运动。
现测得两星中心距离为R,其运动周期为T,求两星的总质量。
(引力常量为G)。
