几种演示影响刚体滚动因素的物理实验仪

Several physics instruments demonstrating the factors affectting a rigid body's rolling

改进和研制了几种演示刚体平面平行运动(滚动)的物理实验仪,突出演示了转动惯量、滚动半径、刚体质量等因素对运动的影响.仪器结构简单,构思巧妙,演示效果良好.

Several new made physics instruments demonstrate a rigid body's plane-parallel motion (rolling) are reported, especially on the functions of the moments of inertia, rolling radius and the mass of the rigid body. Their constructions are simple and wonderful. They achieve a good result.
