Linear motion is fun! Our exploration of linear motion is the highlight of these couple of weeks. Always try the challenge graphs at the end of the labs.
Day 2 (Mon Sept 14):
-
-Linear Motion examples on pg 4 of Prob. Solv. Exercises (PSE)
-
-HW PSE pg 4, #1-3.
Day 3 (Tues Sept 15):
-
-Go over HW
-
-Intro: displacement vs distance
-
-Vector Path mini-lab
-
-HW PSE pg. 5 #4
Day 5 (Weds Sept 16):
-
-Go over HW
-
-Intro to velocity
-
-Read text, sect. 2.1 to 2-4
-
-Hiking problems
Day 6 (Thurs Sept 17):
-
-Go over HW
-
-Discuss FMCE (Force & Motion knowledge check at start of term)
-
-Take FMCE
Day 7 (Fri Sept 18):
-
-Took Linear Motion Quiz #1
Day 8 (Mon Sept 21):
-
-Pre-lab to Graph Matching Lab: how motion detector works, how to set up walking path, meaning of “WU”. Groups drew prediction graphs.
-
-Started Graph Matching Lab
Day 9 (Tues Sept 22 – Autumnal Equinox):
-
-Finished Graph Matching Lab
-
-Worked on additional graph challenges: predicted and measured the motion of carts and other objects.
-
-HW “Colin Sick” Problems
Day 10 (Weds Sept 23):
-
-Went over Colin Sick Problems
-
-Created a table: freefall (from rest) on earth (ignorning air)
-
-Developed & discussed three formulas: General Freefall (Dist) Formula, Two Velocities Form., and Velocity Formula.
-
-Worked Examples in Prob. Solv. bk, pg 8, #1, #2.
-
-HW: do PSE pg. 10, #9-10, read Text 2.4-2.6.
Day 11 (Thurs Sept 24):
-
-Go over HW (PSE, pg. 10 #9-10)
-
-Practiced similar problems Continued Freefall topic.
-
-T worked acceleration examples,
-
-HW: PSE pg 6-7, exercises #5-8
Day 12 (Fri Sept 25):
-
-Warm-up: Two Linear Motion Problems:
-
-1. A marble, released above a distant planet’ surface, is falling at 77.2 m/s 2.8s after release. What is g on the planet?
-
-2. A water cannon fires water upward at 177.5 m/s. How high does it shoot?
-
-Began a demo for projectile motion
-
-HW: PSE pg. 7 #7-8, pg. 12 A-6, A-7, A-12.
Next up: projectile motion
