圆周运动是物理学中的重点和难点,在对圆周运动有充分了解之后,能够解释很多有关圆弧的运动性问题。在学习圆周运动过程中,我们会学习到许多与速度有一定关系的数学符号,如线速度v、角速度w等,在以前对速度的学习中,我们已经得知速度具有一定的相对性,那么在圆周运动当中,线速度具有相对性吗,其所具有的相对性又是相对什么而言的呢,本文根据以上两个问题进行具体的分析。 Circular motion is a key and difficult point in physics. After fully understanding the circular motion, it can explain a lot of questions about the circular motion. During the study of circular motion, we learn many mathematical symbols that have some relationship with the velocity, such as the linear velocity v and the angular velocity w. In the previous study of velocity, we have already learned that the velocity has a certain relativity. Then Among circular motions, is the linear velocity relative, what is the relativity of the relative linear velocity? This article makes a concrete analysis based on the above two problems.
