实验是物理学习过程中必不可少的一个环节.实验能够培养学生的实验素养与探究意识,而橡皮筋因其随手可得且廉价的特点,在许多实验中都有所应用.“力的平行四边形定则”实验中就应用到了橡皮筋.本文通过对力的平行四边形定则实验原理及实验方法的思考,用DIS进行了精确的实验测量,对该实验中使用的橡皮筋问题作了探讨.
Experiment is an indispensable part in the process of physics study.Experiment can cultivate students’ experimental literacy and inquiry consciousness, while the rubber band has been applied in many experiments due to its availability and cheapness. Parallelogram "is applied to the rubber band.In this paper, through the experimental principle and experimental method of parallelogram theory of force, the accurate experimental measurement was carried out with DIS, and the rubber band used in this experiment Exploring.
