1、简单初中物理小制作1、不倒翁器材：常用鸡蛋，胶水，一些重物及装饰物品若干。制作：在鸡蛋的尖顶端开个小孔，用吸管或其他任何方式将蛋清，蛋黄取出，形成较完整蛋壳。将小重物放入鸡蛋中，用胶水固定在底部，用装饰品或颜料将鸡蛋外部按喜好装饰即可。操作及现象：将其左右压倒，仍顽强的恢复到竖直状态。原理解释：不倒翁不会倒,一方面因为它的结构上轻下重,重心很低;另外,当它向一边倾斜时,重心和桌面接触点不在同一条铅垂线上,重力作用会使它摆动回原位置.从杠杆原理来说，不倒翁倒下时，不管支点在哪里，虽然重力的力臂较短，但力矩力力臂，有力矩，不倒翁还是回复到原来位置。还有就是底部为圆形，摩擦力小，便于不倒翁回到原来位

19、小窍门：*弹片的弹性要尽可能好。这样薄片与物体间存在摩擦力的时间就短，减小重物的水平方向微动。*弹片和支架之间的位置要仔细调试。太远，弹片给与的撞击速度不够；太近，要防止弹片撞到重物或支架。*重物和弹片的接触面间要尽可能光滑些。这样可以减小摩擦力，减小重物的水平方向微动。*支架上的支撑面要适当宽些。考虑到重物落下时的速度和水平方向的微动，太窄则可能使得重物的重力作用线偏出支撑面，导致演示失败。精品w o r d 可编辑资料-第 4 页，共 7 页-文档编码:CR5M4N6Q9T1 HN6A2O1Z1Y9 ZG6Q2L2R8Y5文档编码:CR5M4N6Q9T1 HN6A2O1Z1Y9 ZG6Q2
