Does this help answer if it's negative or positive ?

4. Answer the following questions before running the simulation (don't hit the play button yet!): What is the momentum of ball 1? 38 kg*m/s What is the momentum of ball 2? -.38 kg*m/s Why is the momentum of ball 2 negative? Because its velocity is to the left What is the net momentum of the system before Okg*m/s the collision? 5. Now hit the play button, watch the collision, and right after the collision hit the pause button and answer the following questions: What is the momentum of ball 1? -.38kg*m/s What is the momentum of ball 2? 38 kg*m/s Why is the momentum of ball 1 negative? It's velocity is now to the left What is the net momentum of the system after the 0 kg*m/s collision? 6. Define conservation of momentum and explain how this collision demonstrates that momentum is conserved: In an isolated system with no net external force, the total momentum remains constant before, during and after an interaction. Because the net external force is negligible and the forces during impact are internal and equal and opposite, the systems total momentum stays the same
