向量是新教材增加的内容,向量在物理上又称矢量,即既有大小又有方向的量,向量是作为力、速度、加速度、位移等量的大小而引入数学的,它通常更多的在物理上应用,随着人们对向量的理解的加深,向量在人们日常生活及学习中愈来愈显其“举足轻重”的作用,尤其在解决数学问题应用中的作用越来越明显。 Vectors are new additions to new textbooks. Vectors are also physically called vectors, that is, they have both size and direction, and vectors are introduced into mathematics as magnitude of force, velocity, acceleration, and displacement, and they are usually more In physics, as people’s understanding of the vector deepens, the vector becomes more and more obvious in people’s daily life and learning, and its role in solving the problem of mathematical problems is more and more obvious.
