Use the momentum applet here to answer the following questions. Be sure to draw each impact in your notes and include all questions and answers.
1. Press reset and then start. Watch the number for total momentum for the entire interaction. What is the total momentum? Does the total momentum change? Calculate the momentum of mass 1 and mass 2 (p = mv) before the impact and after the impact.
2. Set the speed of mass 2 to zero, press reset to reset the position, and then start the simulation. What is the momentum of mass 1 and mass 2 before the impact? What is the momentum of mass 1 and 2 after the impact? Where did mass 1′s momentum go? Does the total momentum ever change?
3. Set each mass to 2, and Speed 1 to 2 and Speed 2 to -1. What is the momentum of mass 1 and mass 2 before the impact? What is the momentum of mass 1 and 2 after the impact? Where did mass 1′s momentum go? Does the total momentum ever change?
4. Set the elasticity to zero. Set both masses to 1 and speed 1 to 1 and speed 2 to -1. Calculate the momentum of mass 1 and the momentum of mass 2 before starting the simulation. Add them together to find the total momentum. Now run the simulation. Describe what happens in terms of the conservation of momentum.
5. With elasticity still at zero, set Speed 2 to zero, mass 1 to 2 and mass 1′s velocity to 2. Calculate the momentum of each mass before the impact. Run the simulation and describe what happens.
