<P>식은 위와 같은데요....</P>
<P> </P>
<P>문제는 물체 m에 관련된 식을 보면 2m에 의한 관성력은 고려하지 않았습니다. <STRONG>왜 관성력을 고려하지 않아도 되는 것일까요</STRONG>~~~??</P>
<P> </P>
<P>물리고수님들 답변 부탁드리겠습니다.~~(__)</P>

첫댓글 해설에서 제시된식들은 관성계입장에서 세운 운동방정식입니다.
관성계에선 관성력과같은 가상힘을 도입할것없이 물체에작용하는실제힘으로 운동방정식을 서술해요.
해설식은 물체에 작용하는 마찰력으로 운동방정식을 기술했습니다.
보아보아님~~ 감사드립니다.
