noun ダウンロード 🔗共有 角運動量 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. Examples : "A spinning ice skater pulls their arms in to decrease their moment of inertia, causing their angular momentum to stay constant, which makes them spin faster. " スピンするフィギュアスケーターは、慣性モーメントを減らすために腕を内側に引き寄せ、角運動量を一定に保ち、より速くスピンします。 physics energy mass system theory AIとチャット語彙ゲーム読解練習
