摘要
由入射球、被碰球以及弹射结构、斜面轨道结构和靶标结构等,组成一种可利用机械能转化和斜抛运动进行打靶的新型实验装置。本装置实验涉及动量守恒定律、动能定理及机械能守恒定律等物理规律,其设计旨在模拟生活中一类常见的现象——射击打靶,分析碰撞过程以及斜抛运动中所遵循的力学规律。
The experimental device with the function of the mechanical energy transformation and the oblique throwing motion to shot the target,composed of colliding balls,the ejection installation,the inclined plane track unit and the target structure.The experiment of this device involves the conservation of momentum,the kinetic energy theorem,the law of mechanical energy conservation and other physical laws.The design of experimental device aims at simulating a common phenomenon in life——shooting the target,and then studying the mechanical laws followed in the processes of both the collision and the oblique projectile motion.
