每年复课中,同学们总是索要初中物理公式.本文结合中考及新版教材列出100多个公式,并对主要的公式做了简要的注释,以飨读者.一、力学部分1.速度:v=s/t.注释:(1)速度是描述物体运动快慢的物理量,因为运动具有相对性,因此使用该公式应注意参照物的选取,一般以地面为参照物;(2)对于匀速直线运动来说,v与s Each resume class, students always ask junior high school physics formula.This paper combines the senior high school entrance examination and the new textbook lists more than 100 formulas, and the main formula is a brief annotation to readers.First, the mechanical part 1. Speed: v = s / t. Notes: (1) The velocity is the physical quantity that describes the speed of the object. Because the motion is relative, we should pay attention to the selection of the reference object by using this formula, generally taking the ground as the reference; (2) For example, v and s
