Modification of the apparatus of freely falling experiment
Xiaoning Luan · Physics Experimentation · 2010
By adopting the electromagnetic induction principle,some improvements are made for the traditional freely falling experiment apparatus to solve problems such as the influence of remanence,the errors caused by non-horizontal light emission of photoelectric detector and the inconsistency of the light block position of the falling ball.The problem of inaccurate light blocking is also solved.
