力的正交分解在中学物理教学中是一个重要的内容,也是教学的一个难点。本文通过对“正交分解”的浅析,既了解了它在中学物理中的重要地位,又指出学习它能够培养学生的非智力因素、逻辑推理能力、抽象思维能力,对学生的人生同样具有意义。 Orthogonal decomposition of force in secondary school physics teaching is an important content, but also a difficult teaching. Through the analysis of “Orthogonal Decomposition ”, this article not only understands its important position in middle school physics, but also points out that learning it can cultivate students’ non-intellectual factors, logical reasoning ability and abstract thinking ability, Equally meaningful.
