| 摘 要： | 本实验用智能手机App Video Physics追踪小球在竖直平面内做圆周运动的情况,研究了不同质量的小球从同一高度静止释放到达最低点的速度关系,研究了从不同高度静止释放小球的速度与运动轨迹之间的关系,计算了小球在圆形轨道上运动时的向心力、角速度,以及当小球与圆形轨道等高静止释放时小球的脱离点速度. |
| 关 键 词： | 智能手机 Video Physics 视频分析 竖直平面内的圆周运动 |

| Abstract: | The circular motion in a vertical plane of the ball was tracked by a smartphone App"Video Physics".The velocity at the lowest point of the balls of different masses and the relationship between the velocity and the path in different height were obtained.Moreover,the centripetal force,angular velocity of the ball in the circular orbit and the detached point when the ball was released at the same height as the circular orbit was calculated. |
