動畫:自由落體與鉛直面圓周運動(三)(Free body & Vertical Circular Motion) 3 四月, 2011發表留言 此動畫呈現另一種鉛直面圓周運動,與繩擺的結合. 其實此運動的基本觀念與前一個動畫:自由落體與鉛直面圓周運動(二)相同. 可拖曳球到不同高度(與釘子位置的關係)釋放後,觀察其運動型態. ...
在Reset狀態或繩子與釘子不接觸時,可試著拖曳釘子(改變其高度),觀察其運動型態. http://mail2.cjhs.kh.edu.tw/PhysicsElearning/wp-content/uploads/2011/04/VerticalCircleII.swf 重力位能重力位能鉛直面圓周運動 動畫:自由落體與鉛直面圓周運動(二)(Free body & Vertical Circular Motion) 28 三月, 2011發表...

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.;The circular motion in a vertical plane of the ball was tracked by a smartphone APP...
When you have a mass moving on a rope in a vertical circular motion, at the top and the bottom of the swing, the force of tension cleanly takes care of gravity and creates a centripetal force. However, when the mass in the middle of a cycle like so: How does the force of gravity...
