永磁悬浮技术探究匀变速直线运动的规律

摘要

在之前我们所用的气垫导轨探究匀变速直线运动规律的基础上，改进为永磁悬浮技术探究匀变速直线运动的规律，并进一步测得了当地的重力加速度。运用该方法能够有效减少物体运动时的阻力，提高测量精度，方便实验的计算，将电磁学与力学相关知识有效结合，提高实验的综合设计程度。%We use the magnetic levitation technology to explore the law of the uniformly accelerated motion in-stead of the air track technology used formerly,and measure the local acceleration. The measurement mode is the combination of mechanical and electromagnetic modes,and improves the integrated design level of the tra-ditional experiment.
