用半径相同的铁球A、玻璃球B的碰撞来验证动量守恒定律,可有3种方案.方案1:如图1所示,斜槽与水平槽圆滑连接,记录落点的木板平放.图1(1)用天平测出铁球质量m1=16.7g和玻璃球的质量m2=5.4g(m1m2).(2)安装好实验装置,使槽的末端的切线水平,在木板上铺一张白纸,白纸上铺复写纸,用 With the radius of the same iron ball A, glass ball B collision to verify the law of conservation of momentum, there are three options: Scenario 1: As shown in Figure 1, the chute and the horizontal groove connected smoothly, the landing point of the board lay flat. Figure 1 (1) The mass of the ball measured by the balance m1 = 16.7g and the mass of the glass ball m2 = 5.4g (m1m2). (2) The experimental device installed so that the tangential level of the end of the groove, Zhang white paper, white copy paper, with
