Physics - Center of Mass Question with Solution | TestHub

Momentum of the system of $m_1$ and $m_2$ in the ground frame is conserved

Momentum of the system of m₁ and m₂ in the frame attached to the center of mass of m₁ and m₂ is always zero.

The term $\frac{1}{2}\left(m_1+m_2\right)v_C{}^2$ is always constant, where $v_C$ is velocity of center of mass of $m_1$ and $m_2$

Kinetic energy in center of mass frame remains constant
