課程介紹：

物理是一年級第一學期的課程，提供了一個經典力學的引進。它涵蓋了牛頓力學，流體力學，氣體動理論的基本概念。

8.01SC和8.01是不同的。8.01SC每個文件播放的時間比較短。

“力學”這個名詞，在這里是指物體的運動：我們將研究對象的議案如何理解和預測的力量，在對象上。形容詞“經典”，在這種情況下，這意味著我們會限制我們的研究相比，光的速度緩慢的速度，所以我們不會考慮到相對論的影響。這也意味著，我們會限制我們的研究對象一般都很大，比原子或分子，這樣我們就不需要考慮量子理論的影響。幸運的是，我們有可能在日常生活中，以滿足幾乎任何情況下滿足這些限制，因此，經典力學的結果有一個科學和工程應用的多種。
