# 操作定義

(重新導向自 操作型定义)

「花生果醬三明治」的操作性定義是「使用抹刀先將花生醬塗抹到一片麵包上，再將果醬塗抹在花生醬上，最後蓋上另一片厚度相同的麵包後所得到的成果。」

## 質量的操作定義

${\displaystyle F=m_{A}a_{A}=m_{B}a_{B}}$

${\displaystyle m_{B}={\frac {a_{A}}{a_{B}}}m_{A}}$

## 力的操作定義

${\displaystyle F_{s}=-kx}$

${\displaystyle F_{G}=-G{\frac {m_{A}m_{B}}{r^{2}}}}$

${\displaystyle F_{g}=mg}$

## 註釋

1. ^ 使用更基礎的概念來對於術語給予定義。例如，術語「速度」可以用「移動距離」與「時間間隔」來給出定義。[1]
