摘要
给出一种演示刚体在定点运动时角动量与角速度方向的关系,及力矩突变为零时角动量变化规律的实验演示与分析.
The relationship between angular momentum and direction of angular velocity is presented when a demonstration rigid body is doing fixed point movement, and experimental demonstration and analysis of angular momentum variation when moment of force is suddenly changing to zero.
