本文介绍一种研究平抛运动的实验装置.其作用是通过实验,能清晰显示平抛运动的轨迹,便于对各运动参量的研究.概述 如图1所示,一钢球受力沿光滑桌面运动,以一定速度离开桌缘作平抛运动.这个运动可以分解为水平速度u_x和垂直速度为u_y的两个分运动.也可对图2实验装 This article describes an experimental device for studying flat-throwing motion. Its role is to clearly show the trajectory of flat-throw motion through experiments, and to facilitate the study of various motion parameters. Overview As shown in Figure 1, a steel ball is forced along a smooth tabletop Movement, leaving the edge of the table at a certain speed for flat throw. This movement can be decomposed into two sub-movements with horizontal velocity u_x and vertical velocity u_y.
