How to solve for center of mass
WebWhat we're seeing is a very general and powerful rule that applies to calculating the center of mass: if we have two equal masses m_1 = m_2 m1 = m2 at exactly opposite positions, \vec {r}_1 = -\vec {r}_2 r1 = −r2, then their total contribution to the CM is zero. Now let's move on to the continuous case. WebWhat we're seeing is a very general and powerful rule that applies to calculating the center of mass: if we have two equal masses \(m_1 = m_2\) at exactly opposite positions, \(\vec{r}_1 = -\vec{r}_2\), then their total contribution to the CM is zero.
