向量既有大小,又有方向,是数与形的完美结合．向量是数学中的重要概念,并能和数一样进行运算,而且用向量的有关知识能有效地解决数学、物理等学科中的很多问题,向量内容的增加,可解决多年来高中数学教材对向量介绍过简而产生的对物理教学不适应的状况．特别是明显滞后于学习运动学教学的情况会有所改变．这样,使各科教学之间可以互相渗透,有利于综合能办的培养．
Vectors have both size and direction. They are the perfect combination of numbers and shapes. Vector is an important concept in mathematics, and it can be operated in the same way as numbers, and the knowledge of vector can effectively solve many problems in mathematics, physics and other disciplines. The increase of vector content can solve the problem of high school mathematics textbooks for many years. The vector introduces the situation that the physics teaching is not adapted to the short-lived situation. In particular, the situation that obviously lags behind the study of kinematics teaching will change. In this way, the teaching of each subject can infiltrate each other, which is conducive to the cultivation of comprehensive education.
