在現用高一物理課本第31節中寫道:“在地球上每一個地方,1克重和達因相當的數值,就等於那個地方用每秒每秒厘米做單位的重力加速度的數值。在兩極1克重=983達因,在赤道1克重=978達因,在北京1克重=980達因,平均起來差不多是1克重=980達因,1千克重=980000達因”。照這樣說來,作為力或重量的單位的克重,其大小是隨地點的不同而不同的,而1克質量的物體,其重量在地球上任何地方都是1克重,這種說法是不正確的。在物理学中重量或力的單位是必须有確定意義的。在同一本書第29節里也說道:“現
In verse 31 of the current ASN text, it states: “In every part of the earth, a weight of 1 gram and a dyn number equals the value of the gravitational acceleration at that place in units of centimeters per second. The bipolar 1 gram = 983 dyne, 1 gram at the equator = 978 dyne, 1 gram in Beijing = 980 dyne, on average almost 1 gram = 980 dynes, 1 kilogram = 980000 dynes. As such, the weight of a unit of force or weight varies in size from place to place, whereas 1 gram of mass weighs one gram on any part of the globe incorrect. The unit of weight or force in physics must have definite meaning. In verse 29 of the same book, it says: ”Now
