### π΄ 1: T 10/5, π‘ 3: T 10/5 - energy review problems

LAB SAFETY: Students will be using a modified Atwood machine, and if heavy masses are used, injury could result if they fall on a foot. Please pay attention to all lab instructions, and only use equipment for their instructed use.

Daily Check-in: Energy Conservation

Today, we'll start by completing the energy lab we started last time.

Then, we'll do 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

We'll continue on this set next class.

Homework: Energy problems due in βοΈ Google Classroom by Thursday, October 7th. Watch this video for a momentum review:

### π₯ 1: Th 10/7 lab, π¨ 3: W 10/6 lab - energy & momentum problems

Daily Check-in: Elastic Potential Energy vs Hooke's Law Demo

Today, we'll start by finishing any energy problems that you haven't finished from the last set.

Then, 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 energy problems due in βοΈ Google Classroom by Thursday, October 7th. Momentum problems above due in βοΈ Google Classroom by Sunday, October 10th. QUIZ on energy and momentum Monday, October 11th.

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):
