旋轉慣性的意思、翻譯和例句

是什麼意思

「旋轉慣性」是指物體在旋轉運動中保持其旋轉狀態的特性。這個概念源於牛頓的運動定律,特別是第一運動定律,指出一個物體如果不受外力作用,將保持其靜止或均勻直線運動的狀態。在旋轉情況下,物體將保持其旋轉速度和旋轉軸的方向,直到有外力作用於它。這種慣性與物體的質量和形狀有關,通常用於物理學和工程學中來分析旋轉運動的行為。

1:Rotational Inertia

用法:

物體對於改變其旋轉狀態的抵抗能力,通常與物體的質量和質量分佈有關。這個概念在物理學中非常重要,特別是在分析旋轉運動時。旋轉慣性越大,改變物體的旋轉狀態就越困難。

2:Moment of Inertia

用法:

用來量化物體對於旋轉運動的抵抗力,通常依賴於物體的質量和質量分佈。它在物理學和工程學中被廣泛應用,特別是在動力學和機械設計中。不同形狀的物體有不同的轉動慣量。

3:Angular Momentum

用法:

描述物體旋轉運動的量,等於物體的轉動慣量與其角速度的乘積。這個概念在物理學中非常重要,因為它涉及到能量的轉移和保存。在沒有外力作用的情況下,物體的角動量會保持不變。

The athlete changes his angular momentum while turning.

例句 3:

在太空中,物體的角動量不會隨時間改變。

In space, the angular momentum of an object does not change over time.
