이유는 다음과 같습니다.
* 관성 : Objects have an inherent resistance to changes in their state of motion. 이것을 관성이라고합니다.
* 순 힘 없음 : When no forces are acting on an object, there's no external influence to change its motion.
* 일정한 속도 : 가속을 유발할 힘이 없기 때문에 (속도 또는 방향의 변화), 물체는 같은 속도와 같은 방향으로 계속 움직입니다.
예 :
* A ball rolling across a frictionless surface will continue rolling forever at the same speed.
* A spaceship in deep space, far from any gravitational pull, will continue moving at a constant velocity in a straight line.
It's important to note that in real-world scenarios, there are always some forces acting on objects, such as friction or gravity. However, Newton's First Law provides a foundation for understanding how objects behave in the absence of any forces.
