Description
一种中学物理滑轮组实验教具
技术领域
[0001] 本实用新型涉及中学物理教具领域，具体涉及一种中学物理滑轮组实验教具。
背景技术
[0002] 当前，在国家教学改革不断推进实施的潮流下，物理教学已经逐渐增加了实验课 程的实验环节内容。通过结合实验与理论的教学方式，不仅能够使学生掌握的知识更加牢 固，还能够有效提起学生的学习兴趣，使物理教学脱离传统枯燥的理论学习为主的教学方 式，因此，物理教学的相关知识点实验教具的需求也越来越多，而针对实验教学活动的专 用教学用具则相对缺乏;现有的很多有关滑轮组实验的教具滑轮组结构比较分散，不利于 教师进行现场教学演示。
[0003] 基于上述，本实用新型提供一种中学物理滑轮组实验教具，通过实验教具的合理 设计，满足中学物理教师通过实验教具演示和讲解滑轮组原理和实验的课程教学，以解决 现有技术存在的不足和缺陷。 实用新型内容
[0004]本实用新型的目的就在于:针对目前存在的上述问题，提供一种中学物理滑轮组 实验教具，通过实验教具的合理设计，满足中学物理教师通过实验教具演示和讲解滑轮组 原理和实验的课程教学，以解决现有技术存在的不足和缺陷。
