Questions: Part I. Conservation of Linear Momentum 1. The velocity vectors pointing left are negative. What does the negative sign represent? 2. What do you notice about the total momentum before and the total momentum after? 3. Which principle are you demonstrating in number 2? State it. 4. Discuss what is meant by an isolated system and how it is related to the law of conservation of momentum.
