If you want to check your answers, I have hidden the link to the answer key within this unit's optional assignment worksheet (posted a couple of weeks ago - Forces in 1D) Don't look until you have finished trying all the questions!!!
Monday: review of Newton's 2nd law and applications... what if mass or net force are doubled, effect on acceleration, etc. We also had a whole-class demonstration of inertia and direction of net force required to make something accelerate through a curve; accelerating a bowling ball in the hallway with a "force stick" and saw some other centripetal acceleration demos.
Tuesday: Acceleration Races, , answers to homework that was just turned in, and discussion of Tuesday's lunar eclipse (look to the Western horizon when you wake up... visibility will be good until about 6:30ishAM.
(flyers in class for lunar (10/8) and solar eclipse (10/23) data and astronomy club will meet near the football field for both)
Review run-on paragraph worksheet handed out (link above)
Wednesday: Newton's 3rd law and Momentum - notes, demonstrations, practice problems. Newton's 3rd law notes
Answers/explanations to some of our inertia demonstrations and an answer to how much gravitational field the International Space Station is subject to at its altitude... remember, they aren't in zero gravity really.... but they don't feel it because they're falling.... (around) Earth. Video clip of ISS:
Thursday: video clips to support force concepts from this unit, and more practice.
Friday: HMWK due, Quiz!! Topics: acceleration and Newton's laws (don't need to remember which is which, but apply them); Inertia, F=ma, and action-reaction force pairs. Maybe momentum.
