学生进入高中阶段一开始学习物理,首先进行运动学的学习.与之前在初中学的简单物理运动相比有了很大的难度,而这部分又是在高中阶段学习物理的基础和难点.运动学解题的方法多种多样,如果学生在高一时就能掌握图象法解题,在今后的学习和复习都有不可估量的帮助.速度——时间(v-t)描述物体运动的速度随时间的变化规律.其横坐标表示时间、纵坐标表示速度,其斜率表示速度变化的快慢即加速度,而图象与坐标围城的面积是物体运动的位移.
When students enter high school, they begin their studies in physics and begin their studies in kinematics, which is quite difficult compared with the simple physical exercises in junior high schools, which are the basic and difficult points of studying physics in high school. There are many ways to solve a problem, if students can master the image law when they are fresh, they have immeasurable help in future study and review Speed - Time (vt) Describe the speed of the object movement over time The abscissa indicates the time, the ordinate indicates the speed, and the slope indicates the speed of the speed change, that is, the acceleration, while the area of the image and the coordinate surrounding city is the displacement of the object.
