외부의 힘을 받지 않는 고립된 물체 또는 계에서 전체 운동량의 합이 보존된다는 법칙. 자연의 기초적인 법칙이다. 운동량 보존법칙은 에너지 보존법칙과 함께 자연현상을 지배하는 기초법칙이다. 운동의 제2법칙에...
외부에서 힘이 작용하지 않으면 계의 전체 운동량의 합은 변하지 않고 보존된다는 법칙. 법칙은 자연계를 지배하는 법칙 중 기초이며, 완전탄성충돌이나 비탄성충돌 두 가지 모두의 경우에도 항상 성립한다. 이...

In Newtonian mechanics, momentum ( pl. : momenta or momentums ; more specifically linear momentum or translational momentum ) is the product of the mass and velocity of an object. It is a vector quantity, possessing a magnitude and a direction. If m is an object's mass and v is its velocit...

Conservation of momentum, general law of physics according to which the quantity called momentum that characterizes motion never changes in an isolated collection of objects; that is, the total mom...
Laws of Conservation of Momentum ; Law of Conservation of Momentum states that the total momentum of objects before and after collision remains constant. Before stating the Laws of Conservation of Momentum, we must first learn about momentum. The momentum of an object is a physical quantity that is defined as the product of the mass and velocity of the object. Momentum a vector quantity is very useful in Newtonian physics. The laws of Conservation of Momentum explain that the momentum of any system is always constant until an external force is ...
계의 외부로부터 힘이 작용하지 않는다면 계 내부의 전체 각운동량이 항상 일정한 값으로 보존된다는 법칙이다. 반지름과 회전 속도가 반비례하며 회전하는 피겨스케이팅 선수의 회전동작이 대표적인 예이다.
The conservation of momentum is a fundamental concept of physics along with the conservation of energy and the conservation of mass. Momentum is defined to be the mass of an object multiplied by the velocity of the object. The conservation of momentum states that, within some problem domain, the amount of momentum remains constant; momentum is neither created nor destroyed, but only changed through the action of forces as described by Newton's laws of motion. Dealing with momentum is more difficult than dealing with mass and energy because mome ...
