摘　　要：惯性定律也称作牛顿第一定律,是经典物理力学中的几大重要定律之一。静止的物体具有惯性,运动的物体也具有惯性。新设计的运动物体的惯性现象演示装置通过调速直流电机带动丝杆滑台水平移动,安装在滑台上的金属小球下落装置能很好地演示静止的和运动的物体都有惯性。仪器结构简单,操作简便,现象直观,能为惯性定律教学助一臂之力。The law of inertia,also known as Newton’s first law,is one of the most important laws in classical physical mechanics.Static objects have inertia,and moving objects also have inertia.The newly designed demonstration device of inertia phenomenon of moving objects drives the screw slide table to move horizontally through a speed regulating DC motor.The metal ball falling device installed on the sliding table can demonstrate static and moving well.All objects have inertia.The instrument is simple in structure,easy to operate and intuitive in phenomenon.

关 键 词：惯性定律 静止 运动 惯性 演示装置
