研究平抛物体的运动轨迹的学生实验,是采用描点怯描出运动轨迹的。为了能直接将平抛物体的运动轨迹呈现在学生面前,下面提供一种简便可行的方法。实验器材:1.斜槽;2.45×60厘米的磁性写字板(可到工厂定制,也可用8块儿童磁性写字板拼接而成);3.将一根磁性较强的小棒嵌入直径为1.5厘米的硬木球(即可避免下落时磁棒与地直接相碰,又可防止
The student’s experiment for studying the trajectory of a plane-throwing object is to trace the motion trajectory with a sketch. In order to directly present the trajectory of the plane-throwing object to the students, the following provides a simple and feasible method. Experimental equipment: 1. Chute; 2.45 × 60 cm magnetic writing board (can be customized to the factory, but also can be assembled from 8 children’s magnetic writing board); 3. Insert a magnetic rod into a diameter of 1.5 Centimeter hardwood ball (can avoid direct collision between the magnet and the ground when falling, but also can prevent
