定量验证牛顿第三定律

摘要

通过2台电子天平的示数变化，定量地探究作用力与反作用力的关系，验证压力、浮力、磁力等多种形式的力均满足牛顿第三定律。%The relationship between action and reaction was quantitatively explored by the changes of the display of the two electronic balances ,and all kinds of forces ,such as pressure ,buoyancy and magnetic force ,were verified to obey Newton third law .
