Solving Momentum Problems from the Center of Mass Reference Frame
When it comes to solving momentum problems, especially in collisions or explosions, using the center of mass (CoM) reference frame can simplify even the most complex interactions. In this post, we’ll walk through how to solve these problems step by step and explore why the CoM reference frame is such a powerful tool in physics.
