Would a spring scale carried to tml . p/z :p-;xxg(lboohe eu*zmmng n3qar9c 616 Moon give accurate results if the scale had been calibrated (a) in poue1 mz9 agc3u6mn*nqr6nds, or (b) in kilograms?
参考答案: Only the pounds reading would be correct. The spring scale works on the fact that a certain force (the weight of the object being weighed) will stretch the spring a certain distance. That distance is proportional to the product of the mass and the acceleration due to gravity. Since the acceleration due to gravity is smaller by a factor of 6 on the moon, the weight of the object is smaller by a factor of 6, and the spring will be pulled to only one-sixth of the distance that it was pulled on the Earth. The mass itself doesn’t change when moving to the Moon, and so a mass reading on the Moon would be incorrect.
