名事情, 物质动要紧维物质

物质是一個科學上沒有明確定義的詞，一般是指靜止質量不為零的東西。物质也常用來泛稱所有組成可觀測物體的成份。
所有可以用肉眼看到的物體都是由原子組成，而原子是由互相作用的次原子粒子所組成，其中包括由質子和中子組成的原子核，以及許多電子組成的電子雲。一般而言科學上會將上述的複合粒子視為物質，因為他們具有靜止質量及體積。相對的，像光子等无质量粒子一般不視為物質。
物質常見的物質狀態有四種：固體、液體、氣體及等离子体。不過實驗技術的進步產生了許多新的物質狀態，像是玻色–爱因斯坦凝聚及费米子凝聚态。對於基本粒子的研究也產生了新的物質狀態，像是夸克-膠子漿。
愛因斯坦證明所有物體都可以轉換為能量（即質能等價），之間的關係式即為著名的，其中為能量，為質量，為光速，其數值為299792458 m/s。因此很小的質量可以轉換為很大的能量，例如正子和電子（都是物質）可以轉換為非物質的光子。
