学习了浮力的知识,我想知道浮力的大小到底和什么有关,于是进行了下面的探究。提出问题浮力的大小和什么因素有关。根据自己的经验我进行了猜想:在游泳时,越往深处走,感觉身体越轻,一定是浮力增大了。鸡蛋在水里面是沉入水底的,而在盐水中能够漂浮,浮力的大小和液体的密度一定有关。于是做出了如下猜想。猜想①浮力的大小和物体所处的深度有关。②浮力的大小和液体的密度有关。设计实验我计划用弹簧测力计测出物体的重力
I learned the knowledge of buoyancy, and I wanted to know what the size of the buoyancy was and what did I do, so I made the following exploration. Question the size of buoyancy and what factors. According to my own experience, I made the conjecture: When swimming, go deeper, feel the body lighter, it must have increased buoyancy. Egg in the water is submerged in the water, and can float in the brine, the size of the buoyancy and the density of the liquid must be related. So made the following guess. Guess the size of the buoyancy and the depth of the object. ② The size of the buoyancy and the density of the liquid. Design Experiment I plan to use a spring dynamometer to measure the weight of an object
