1. Read pages 50-52, and write down 2 important things that you read a. On p. 56 do Review Questions #9, 10, 11, 12, 13, 15, 16 b. On p. 57 do Plug and Chug #1, 2, 4, and 5 c. On p. 57 do Think and Explain #5 Due tomorrow:
1. Read pages 43-49, and write down 5 important things that you read a. On p. 56 do Review Questions #4, 5, 6, 7, 8 b. On p. 57 do Think and Explain #1, 4, 7 This information should be EASY. If something has momentum, if we don't push on it, the momentum doesn't change. So, it will keep moving with the same speed. If something does NOT have momentum, then it will have no momentum UNTIL we push on it. Due today, Monday 12/15 was the review sheet for the quiz. We may check that again tomorrow. The previous HW about the momentum conservation lab: Due on Tuesday, 12/9 was a one page summary of the lab and lab results. You may want to try these starters: "The law of conservation of momentum says that the momentum of the cars _________" "In the first collision, the momentum of the cars before was ____________. Afterwards, we measured the momentum of the cars to be _____________" "Our results for the first collision showed __________. Since our hypothesis was that the total momentum before the collision should be the same as the total momentum after the collision, the results from the first collision (do/do not) support my hypothesis. " Include the results for ALL THREE collisions. Due today is the following. Prepare for a quiz...
1. Read pages 91-93, and write down 3 important things that you read a. On p. 100 do Review #10 b. On p. 101 do Plug and Chug #3 c. On p. 101 do Think and Explain #4 and #5 d. On p. 102 do Think and Solve #3 and #6 The quiz will cover impulse, Ft, change in momentum, and how to calculate Force from change in momentum and time. We worked on the TWO ideas about changing momentum. Force times Time CAUSES a change in momentum. And momentum after minus momentum before tells us how MUCH momentum change there was.
The first part of the HW is to do #4 from the problem sheet (describing HOW the momentum changed on one of the videos) The second part is book work: 1. Read pages 87-90 and write down 3 important things that you read a. on p. 100 do Rev #7, 8, 9 b. on p. 101 do Plug and Chug #1, 2 c. on p. 101 do Think and Explain #2, 3 d. on p. 102 do Think and Solve #2 |
