noun
law of conservation of angular momentum
A fundamental principle in physics stating that the total angular momentum of a closed system remains constant in the absence of external torque.
角運動量保存の法則は、フィギュアスケートのスピンでよく説明される。
The law of conservation of angular momentum is often explained using a figure skater's spin.
Refers to the conservation of linear momentum, whereas 角運動量保存の法則 concerns rotational motion.
The law of conservation of energy, a separate but related conservation law in physics.
A compound of 角運動量 (angular momentum), 保存 (conservation), and 法則 (law). The term is a direct translation of the English 'law of conservation of angular momentum'.
