有人在大学物理中应用牛顿运动定律解决问题的方法,归结为“四个什么”,即“什么物体,在什么力作用下,对什么参照系,作什么运动?”一旦“四个什么”弄清楚了,问题就能够获得解决,我认为对于高中物理运动定律解题方法的教学,“四个什么”同样十分必要。当然,教学时应掌握好尺度,不可逾越教纲。 Some people use Newton’s laws of motion to solve problems in college physics, which boils down to “four things,” namely, “what objects, under what forces, what frame of reference, what kind of movement?” once “four whats” Clearly, the problem can be solved. I think that the “four things” is also very necessary for the teaching of the method of solving problems in the laws of high school physics. Of course, teaching should be well-scaled and should not go beyond teaching.
