从摩天轮的速度是外力作用的结果,研究物体失重和超重与外力的关系。向水杯中倒入不同质量的水,置于电子秤上称量并观察弹簧振动的周期和振幅,发现弹簧振子上升时失重,弹簧振子下降时超重;超重时离开原点的距离越远,则质量越大,同时超重与失重现象越明显。还有,当外力的影响超出物体质量对超重与失重的影响时,存在“外力越大,弹簧振子的超重与失重变化幅度越大”的现象。
From the speed of the Ferris wheel is the result of external forces, study the relationship between body weight loss and overweight and external forces. Pour different quality water into the cup, place it on the electronic scale to weigh and observe the period and amplitude of the spring vibration, and find that the spring vibrator loses weight when it rises, and the spring vibrator descends too much; when the overweight is away from the origin, the mass The greater the greater the weight and weight loss at the same time the more obvious. Also, when the influence of external force exceeds the mass of the object to the effect of overweight and weightlessness, there is a phenomenon that the larger the external force, the greater the change of the overweight and weight of the spring vibrator.
