angular momentum

英語（米国） (en-US) 英語（イギリス） (en-GB)

名詞

(physics) The vector product that describes the rotary inertia of a system about an axis and is conserved in a closed system. For an isolated rigid body, it is a measure of the extent to which an object will continue to rotate in the absence of an applied torque.

日本語の意味

角運動量：物体やシステムが回転する際の運動量で、物体の回転運動の慣性や継続性を示すベクトル量。 / 閉じた系においては保存される量であり、外部からのトルクがない限り回転運動が持続する性質を持つ。
