  1. What is momentum? How do you calculate momentum?<\/li>\n
  2. What is impulse? How do you calculate impulse?<\/li>\n
  3. Which has more momentum: a car moving at 50 mph or a truck moving at 50 mph? Why?<\/li>\n
  4. Which has more momentum: a car moving at 40 mph or the same car moving at 60 mph? Why?<\/li>\n
  5. Why is it important to follow through when hitting a baseball or when hitting a golf ball?<\/li>\n
  6. Why is it helpful to make car dashboards out of soft material instead a harder material?<\/li>\n
  7. A cannonball is fired out of a cannon. How are the forces felt by both objects related?\u00a0 How are the impulses felt by both objects related?<\/li>\n
  8. What happens when there is an elastic collision?<\/li>\n
  9. Rank the most momentum from highest to lowest: a baseball moving at 50 mph, a car moving at 45 mph, a worm moving at 0.1 mph, or a building.<\/li>\n
  10. A train rolls along a track with considerable momentum. If the mass of the train were tripled (x3) and the speed of the train was kept the same as before, how would the momentum change?<\/li>\n
  11. If a cannon shoots a cannonball, why does the cannonball move really fast and the cannon only travels back at a slow speed?<\/li>\n
  12. If you drop a 5 kg ball and a 10 kg ball from the same height, how will their accelerations compare to each other? What about their speed?\u00a0 What about their momentum?<\/li>\n
  13. Can you safely jump off a building wrapped in bubble wrap?<\/li>\n
  14. If an apple bounces off the ground, will it apply more force or less force than if it did not bounce? Hint: look at the types of collisions we\u2019ve studied.<\/li>\n
  15. A moving train crashes into an identical train at rest. If they couple together, how will their combined velocity compare to the original velocity of the first train?<\/li>\n
  16. A piece of putty crashes into a bowling ball at rest with 4 kgm\/s. After sticking together, how much combined momentum will they have?<\/li>\n
  17. How does a rocket ship accelerate up? (Hint: What does it have to do?)<\/li>\n
  18. If Superman is at rest in outer space and pushes a giant asteroid away, what will move away faster? Who will have more momentum?<\/li>\n
  19. A 5 kg ball is thrown at 20 m\/s. What\u2019s the ball\u2019s momentum?<\/li>\n
  20. A ball is moving at 18 m\/s and has a momentum of 54 kgm\/s. What is mass of the ball?<\/li>\n
  21. If you drop a bouncy ball and a piece of putty from the same height, which will have a greater impulse when they hit the ground? Why? (Hint: look at types of collisions)<\/li>\n
  22. A 5 kg ball moving at 3 m\/s crashes into a 6 kg ball which is initially at rest. If they stick together, what would be their combined momentum after the crash?\u00a0 What would be their speed after the crash?<\/li>\n
  23. A model rocket shoots 250 kg of gas downward at a speed of 30 m\/s. What speed would the rocket travel upwards at, if it has a mass of 100 kg?<\/li>\n
  24. A 2 kg cannonball leaves a cannon at 15 m\/s. If the cannon has a mass of 8 kg, how fast would the cannon be moving backward?<\/li>\n
  25. A 12 kg car (moving at 3.5 m\/s) travels and hits a 2 kg frog (which is not moving to begin with). If they \u201cstick together\u201d what would be their combined speed?<\/li>\n
  26. A 5 kg car is moving right at 3 m\/s towards a car that is not moving. If after colliding, the 5 kg car stops, then how much momentum will the second car gain?\u00a0 How much mass would it have if it then traveled at a speed of 6 m\/s?<\/li>\n
  27. If you push a 120 kg refrigerator with 80 N for 5 seconds, what will be its velocity? Hint: You may need to use multiple equations.<\/li>\n
  28. A 20 kg ball moving at 13 m\/s to the right hits another 5 kg ball initially stopped. If after the collision, the 20 kg ball moves at 2 m\/s, then how much momentum should the 5 kg ball have?<\/li>\n
  29. A car stopped by a wall takes 0.3 seconds to stop. The same car at the same speed takes 0.7 seconds to stop when going through a haystack.\u00a0 How does the impulse of the first car compare to the impulse of the second car?<\/li>\n
  30. A ball was hit by a bat with a force of 320 N for a time of 0.4 seconds. What would be the impulse felt on the ball?\u00a0 What would be the impulse felt on the bat?<\/li>\n<\/ol>\n","protected":false},"excerpt":{"rendered":"
