Today, we'll continue working on the following problems from Chapters 7 and 8 in Halliday to review energy problems from last year. If you haven't watched the videos from last night, do that first, and follow the steps for making a "before and after diagram" for every energy conservation problem.
Support: Ch 7 #32, 36, 45; Ch 8 #19, 21, 36, 52, 55
Required: Ch 7 #30,54, 62, 65; Ch 8 #30, 34, 56, 57, 63, 91
Enrichment: Ch 7 #79; Ch 8 #33, 35, 75, 78
With any time remaining, start the next set on Momentum.
Daily check-in: momentum questions
Today, we'll review momentum by doing the following problems from Chapters 9 to review momentum problems from last year.
Support: 18, 22, 39, 58
Required: 32, 38, 42, 44, 48, 59, 117
Enrichment: 20, 69, 83
Homework: Finish momentum problems above.
Watch the following demonstration. Think about why my daughter appears stronger than me! (I was actually pushing pretty hard!)
There are two additional videos to watch tonight (total is still under 20 min):
Today, we'll apply the concepts of torque and static equilibrium to find the mass of a meterstick. If you still need help here, watch the following video.
Handout: Torque Meterstick Lab
Simulation Alternative: PhET Balancing Act - Part 1 can be done using this simulation if you do not have the materials. You'll have to partner with someone in your lab group for part 2 if you don't have physical materials.
Homework: pd 3: Watch the following video on Torque Equilibrium Problems. Also, read the following webpage on Vector Multiplication. Remember that to calculate torque, we use a cross product. Review the right hand rule.
Today, if you have not finished the lab, you'll finish that first.
Then, we'll work on some simple torque problems. Finish page 1 of the Torque Packet.
Homework: Finish page 1 of the Torque Packet. pd 1: Watch the following video on Torque Equilibrium Problems. Also, read the following webpage on Vector Multiplication. Remember that to calculate torque, we use a cross product. Review the right hand rule.
