目前,在做单摆演示实验时,许多教师通常是在讲台上用线拴金属小球并悬吊在铁架上做演示实验。由于线长是1 m左右,故演示时教室后面的学生看不清楚,可观度不高;还有,当小球运动时,小球运动的偏角、最高点和平衡位置学生只能凭空想像,没有直观性。怎样用最简单的装置来解决以上问题呢?现笔者就向大家介绍一种改进装置。
At present, many teachers, usually performing pendulum demonstration experiments, usually perform the experiment on the podium by tethering metal balls and hanging them on a metal frame. Because the line length is about 1 m, students behind the classroom can not see clearly when demonstrating, and the observability is not high. Also, when the ball moves, the declination, the highest point and the equilibrium position of the ball movement can only be imagined , Not intuitive. How to use the most simple device to solve the above problems? The author will introduce to you an improved device.
