Speed and Average Speed

Abstract

The word "sports" has different meanings in different contexts. Motion in physics refers to the change in the position of an object. As shown in the figure, the object was originally in the A position, and then reached the B position, we say that the object is moving. If the object reaches the position B along a straight line, the object is said to be moving in a straight line; if the object is along a curve to the position B, the object is said to be moving in a curve. Linear motion is the simplest, so we are currently studying linear motion. So, what are we going to study about sports? Chapter first to study the speed of movement. For example in body weight -. In the second race, I was worse than the athletes slapping the speed. The speed at the beginning of the game is indicated by the speed of the sky, the faster after the exercise is called the high speed; the slow after the exercise is the Jianxia small. So, how can we know that the moving body is moving fast, weaving and seeing slowly? The method of studying the speed of exercise and showing peers determines the comparison of pollution, and there are two ways to compare, please see the following examples: Example 1: Field, Movement
