請問磅秤有多重要怎麼看，我一直覺得只有800gw

例题 19 虎克定律的活用 已知指針式磅秤由秤盤、理想輕彈簧、秤 座構成,且指針轉一圈為900 gw。物研社 同學為測量磅秤本身的重量,採用的步驟 及測量結果如下: A 日 由步驟1,2,可測得秤盤重1000W 步驟一:將磅秤正立,指針指向刻度0 步驟二:將磅秤橫放在光滑之水平地面,彈簧呈水平,此時彈簧為自然長度不彎曲, 指針逆轉指向刻度 800 gw 步驟三:將磅秤倒立,指針順轉指向刻度 700 gw 依據以上資料,此磅秤的總重(包含秤盤與秤座)為多少gw? (A) 900 (800 (C) 700 TEL600 (F) 500。 步驟2.3.可測得秤座重700+100=800g w 故磅秤 = 100+800 = 900gm A=1B) eee ele 虎克定律的形 高空彈跳是 地。高空彈器 會伸展產生 的過程中, 為了安全 等。以國 不能比4 (1) 附圖 度量 (2) 小 (3)由 甲 求
