物理公式总结从对于匀变速直线运动的最基本公式出发得出的五个公式

物理公式 — 匀变速直线运动五大公式

一、基本公式

1. 速公式：$v = v_0 + at$

2. 位移公式：$x = v_0 t + \dfrac{1}{2}at^2$文章源自公式库网-https://www.gongshiku.com/html/201908/wuligongshizongjiecongduiyuyunbiansuzhixianyundongdezuijibengongshichufadechudewugegongshi.html

3. 速-位移公式：$v^2 - v_0^2 = 2ax$文章源自公式库网-https://www.gongshiku.com/html/201908/wuligongshizongjiecongduiyuyunbiansuzhixianyundongdezuijibengongshichufadechudewugegongshi.html

4. 平均速公式：$\bar{v} = \dfrac{v_0 + v}{2} = \dfrac{x}{t}$文章源自公式库网-https://www.gongshiku.com/html/201908/wuligongshizongjiecongduiyuyunbiansuzhixianyundongdezuijibengongshichufadechudewugegongshi.html

5. 位移-平均速公式：$x = \dfrac{v_0 + v}{2}\cdot t$文章源自公式库网-https://www.gongshiku.com/html/201908/wuligongshizongjiecongduiyuyunbiansuzhixianyundongdezuijibengongshichufadechudewugegongshi.html

二、自由落体运动

$v_0 = 0$，$a = g$文章源自公式库网-https://www.gongshiku.com/html/201908/wuligongshizongjiecongduiyuyunbiansuzhixianyundongdezuijibengongshichufadechudewugegongshi.html

$v = gt$文章源自公式库网-https://www.gongshiku.com/html/201908/wuligongshizongjiecongduiyuyunbiansuzhixianyundongdezuijibengongshichufadechudewugegongshi.html

$h = \dfrac{1}{2}gt^2$文章源自公式库网-https://www.gongshiku.com/html/201908/wuligongshizongjiecongduiyuyunbiansuzhixianyundongdezuijibengongshichufadechudewugegongshi.html

$v^2 = 2gh$文章源自公式库网-https://www.gongshiku.com/html/201908/wuligongshizongjiecongduiyuyunbiansuzhixianyundongdezuijibengongshichufadechudewugegongshi.html

三、竖直上抛运动

$a = -g$文章源自公式库网-https://www.gongshiku.com/html/201908/wuligongshizongjiecongduiyuyunbiansuzhixianyundongdezuijibengongshichufadechudewugegongshi.html

$v = v_0 - gt$文章源自公式库网-https://www.gongshiku.com/html/201908/wuligongshizongjiecongduiyuyunbiansuzhixianyundongdezuijibengongshichufadechudewugegongshi.html

$h = v_0 t - \dfrac{1}{2}gt^2$

最高点：$h_{max} = \dfrac{v_0^2}{2g}$，$t = \dfrac{v_0}{g}$
