C左,唔係算係好彩定唔好彩
Phy question:
A simple pendulum and a vertical mass-spring system are set into oscillations at the equator.Discuss the change in the period of oscillation,if any,for each system if both are set to oscillate at the poles.(Assume that the string of the pendulum is inextensible and the spring is of negligible mass.Neglect air resistance.)
Can anyone explain y the spring is assumed to have no mass?

你兩個月前問我仲會識GE...NOW差唔多俾番晒老師LU
PERIOD好似有公式,同個g有關
地球係兩極好似平D,近D個DENSE CORE
仲有係赤道,有部分Gravitational force用左黎做向心力,個g都會細左
有錯漏請指教

>simple pendulum
係赤道，個 g 會細ｄ，而 simple pendulum個週期同 g 有關；
但 vertical mass-spring system 個週期 同 g 無關。

如果彈簧有質量... 會令 T^2 - m 線圖穿不過原點。
