伽利略斜面实验是经典的理想实验,其现行教科书中的理论解释存在欠缺。定量探究了伽利略斜面实验中小球的受力、运动状态、能量转化,结果表明:仅受静摩擦,小球可沿斜面上滚至等高处;给出了伽利略斜面实验合理解释的要点,提出了相应的教学建议。
Galileo slope experiment is a classic ideal experiment, the existing textbooks in the theoretical interpretation of the lack of. Quantitatively, the force, the movement state and the energy transformation of the pellets in the Galilean slope experiment are quantitatively studied. The results show that the pellets can roll to the contour along the slope only by the static friction. The points that the Galilean slope experiment can reasonably explain are given. Corresponding teaching suggestions.
