Day 97
ESSENTIAL QUESTION: Momentum - Is It Conserved?
Goals: SWBAT...
1. To consider how impulse and momentum are related to collision injury reduction
2. To design/build/test a crash barrier which reduces the impact force during a collision
3. To explain, with theory and math, how to prove their crash barrier was successful/unsuccessful
Warm-Up 97 (5min):
If you have time to do the warm up today, great. Do it. If not, you can do it for homework.
Reflection on yesterday:
1. How did your crash barrier work yesterday? Rank its success from 1(unsuccessful) to 10(perfect)
2. What modifications did you make?
3. Why did you make those modifications?
4. Were your modifications successful?
