《物理教学》1982年第2期刊有卢立章同志所写“谈谈单摆周期公式T=2π (l/g)~(1/2)中g的取值”一文(以下简称卢文)。卢文抓住T=2π (l/g)~(1/2)式中的g值是摆球静止在平衡位置时,与悬线拉力相平衡的力所对应的加速度值这一特点,把单摆振动周期的公式从引力场推 “Physics Education” published in the 2nd issue of 1982 by Comrade Lu Lizhang “Talking about the value of g in the formula of single pendulum cycle T=2π (l/g)~(1/2)” (hereinafter referred to as Lu Wen) . Lu Wen grasps that the value of g in the formula T=2π (l/g)~(1/2) is the acceleration value corresponding to the force balance with the suspension line when the pendulum ball is in the equilibrium position. The formula for the oscillation period of a single pendulum is pushed from the gravitational field
