一、重力加速度的影响电子天平实际称量的是物体质量,而不是物体重量。也就是说,任意一台天平,无论它放置在地球上的任何地方、任何高度,在任何时间称量同一物体,由于物体本身的质量不变,那么称量结果都应该是相同的。然而,由于地心引力的存在,任何物体本身的重量都会受到重力加速度g的影响,即F=mg。而随着物体在地球上的位置不同,其到地心的距离也不同,那么作用在物体身上的重力加速度g值也不相同。因此,同 First, the impact of the acceleration of gravity The actual weighing electronic scales is the quality of the object, not the weight of the object. In other words, any one balance, whether it is placed anywhere on the earth, at any height, weighing the same object at any time, the weighing results should be the same because of the same quality of the object itself. However, due to the existence of gravity, the weight of any object itself will be affected by the acceleration of gravity g, ie F = mg. With the different positions of the objects on the earth, the distance from the earth to the earth is also different, so the value of the gravitational acceleration g acting on the objects is not the same. Therefore, the same
