摆球大角度摆动实验规律研究

A Study of Pendulum Globe's Swaying Rule at Big Angle

中学物理实验条件下,至少在摆角不超过15°时,各种摆角下测出的周期T及重力加速度g没有明显变化。在3%的误差范围内,同样无法判定g与摆球质量m之间存在联系。

T period and g acceleration due to gravity didn＇t change apparently at different angles under the condition of physical experiment in middle school, at least when angle was no less than 15°. Meanwhile, within the error range of 3%, the connection between acceleration due to gravity and the mass of pendulum globe cant be judged.
