The relation for elastic 1D collision become very simple if viewed from center of mass reference frame.

Before collision: two particles with mass and velocity as m_1,\vec{v_1} and m_2,\vec{v_1}
After collision: the velocity have been changed to \vec{v_1}' and \vec{v_2}'

The center of mass X_{cm}= \frac{(m_1*x1+m2*x2)}{(m_1+m_2)}
\vec{V}_{cm}= \frac{(m_1*\vec{V_1}+m2*\vec{V_2})}{(m_1+m_2)}

\vec{V_1}'-\vec{V}_{cm}=\vec{V}_{cm}-\vec{V}_1=-(\vec{V}_1-\vec{V}_{cm})

\vec{V_2}'-\vec{V}_{cm}=\vec{V}_{cm}-\vec{V}_2=-(\vec{V}_2-\vec{V}_{cm})

  • Please feel free to post your ideas about how to use the simulation for better teaching and learning.
  • Post questions to be asked to help students to think, to explore.
  • Upload worksheets as attached files to share with more users.
Let's work together. We can help more users understand physics conceptually and enjoy the fun of learning physics!
