伽利略理想斜面实验是建立牛顿第一定律的重要依据 .由于没有合适的实验器材 ,多数教师在教学中采用如下教法 :一、斜面下方的水平面上分别放上毛巾、棉布、平滑的桌面 ,让小车三次从斜面的同一高度滑下 ,小车在水平面上的滑行距离依次变大 ,然后让学生假想如果桌面是光滑且足 The Galileo ideal slope experiment is an important basis for establishing Newton’s first law. Because there is no suitable laboratory equipment, most teachers use the following teaching methods in teaching: First, put towel, cotton, and smooth tabletop on the horizontal plane below the slope, letting The car slid down from the same height of the slope three times. The taxiing distance of the car on the horizontal surface became larger in turn, and then let students imagine that if the desktop is smooth and full
