SUMMARY
The discussion centers on the conservation of momentum in elastic collisions, specifically addressing the correct application of velocity signs. When calculating momentum, velocities must be assigned negative values for objects moving in the opposite direction. For instance, if mass one has a velocity of +5 m/s to the right, mass two should be assigned -3 m/s to indicate it is moving left. After the collision, if mass one moves left, its velocity is -1 m/s.
