受力分析
牛頓第一、三定律
一切物體在沒有受到力的作用時,總是保持靜止狀態或等速直線運動狀態
慣性:物體保持原有運動狀態不變的性質
相互作用的兩個物體之間的作用力與反作用力總是大小相等,方向相反,作用在同一直線上
力的作用是相互的
力如何改變運動
設計實驗
無摩擦力,無空氣阻力的環境
在地面上放一個物體,並給物體一個向右的力
物體動了起來,而且速度越來越快
改變物體的密度
運動狀態不改變
改變物體的質量
運動狀態改變
質量增大至原來的兩倍,加速度減小到原來的1/2
牛頓第二定律
物體加速度的大小跟作用力成正比,跟物體的質量成反比
質量不變,力越大,加速度越大
力不變,質量越大,加速度越小
力為0,加速度為0時,速度不變(牛頓第一定律)
F=ma
m : 物體的質量
a : 加速度
F : 物體受到的力
受力分析
重力
大小
G=mg
G : 重力
m : 質量
g : 加速度
一般取9.8或10
方向
豎直向下
彈性
物體發生彈性形變,由於要恢復原狀,對與它接觸的物體所產生的作用
受不受彈性
反推
方向
恢復形變方向
大小
維持物體原本的運動狀態所需的大小
