摘　　要：静摩擦力是高中物理教学中的重要内容.受滑动摩擦力的影响,学生也会错误地认为接触面的粗糙程度以及正压力会影响静摩擦力的大小.但人教版必修第1册“摩擦力”一节设计的静摩擦力演示实验,这个实验效果不能解决学生的疑惑.利用“滴水装置”并结合数字化技术,创新设计静摩擦力的探究实验,帮助学生正确认识静摩擦力,培养和发展学生的科学探究能力和科学思维习惯.Static friction is an important part of physics teaching in high school.Affected by the sliding friction,students will also mistakenly believe that the roughness of the contact surface and the pressure will affect the static friction.But static friction demonstration experiment designed in the section of“Friction”in Book 1,a compulsory course of People′s Education Press,cannot solve students′doubts.By using the“dripping device”and combining with digital technology,innovative design of static friction inquiry experiment can help students correctly understand static friction,cultivate and develop students′scientific inquiry ability and scientific thinking habits.

关 键 词：静摩擦力 最大静摩擦力 数字化
