猎人抓猴是大多数物理教师喜爱的演示实验.这里我提出一种方法,你不妨立即试一试. 把物理教科书填在方桌的两条腿下,使桌面成为斜面,如附图所示.用一根1米长的V形铸铁棒当作猎人的抢.把这铁棒的一端微微抬起.使与桌面成一小角度.并且瞄准静止的猴(且以学生捏住的钢球珠作为猴).让你的钢球子弹沿倾斜的枪管滚下,直奔目标猴,当子弹落到桌面上发出“嘭”的一声时,猴看到子弹飞来,急忙从树上跳下来(学生放手,让钢球珠落下),猴以直线往 Hunter catching monkeys is a favorite demonstration experiment for most physics teachers. Here I present a method that you may wish to try right away. Fill the physics textbooks under the two legs of the square table so that the desktop becomes a bevel, as shown in the attached figure. Use a 1-meter-long V-shaped cast iron rod as a hunter's grab, raise one end of the iron rod slightly, make a small angle with the tabletop, and aim at the still monkey (with the ball of steel pinched by the student as Monkey.) Let your steel ball bulge down the inclined barrel, straight to the target monkey, when the bullet landed on the desktop issued “嘭 ” sound, the monkey saw the bullets flying, hurriedly jump from the tree Down (students let go, let the ball of steel fall), the monkey to a straight line
