一、本月知识学习指要1.要正确理解位移、速度、加速度的概念,及物体运动的相对性、瞬时性、叠加性、矢量性.2.要注意几个易混概念的辨析,如“位移和路程”,“时间和时刻”,“速度和速率”,“瞬时速度和平均速度”,“速度、速度的增量和加速度”等.3.要正确理解?
First, this month’s knowledge study refers to 1. It is necessary to correctly understand the concepts of displacement, velocity and acceleration, and the relative, instantaneous, additive, and vectorial nature of the motion of objects. 2. Should pay attention to the analysis of several miscible concepts, such as “displacement and distance”, “time and time”, “speed and speed”, “instantaneous speed and average speed”, “increase in speed and speed, and acceleration”. 3. To understand correctly?
