### π’β 6: M 11/15, π΅β 8: M 11/15 - Newton's Second Law textbook problems

QUIZ on freefall TODAY!

Today, after the quiz, we'll apply Newton's Second Law by collaboratively completing the problems in Chapter 4 of the textbook:

Problems: Pages 135-136, #16, 21-23, 26, 28, 30

Homework: Finish all of the above problems. Problems are due to βοΈ Google Classroom on Wednesday, November 17th.

### π© 6: W 11/17, π¦ 8: T 11/16 - elevator intro

Today, we'll learn about a class of problems called "elevator problems." You'll learn that a bathroom scale does not really measure your weight in all situations.

Then, do Big Newton's Law Packet page 3 #1-5 (skip #1b) (SOLUTIONS to p 3 of Packet). Watch the following 10-minute video which may be useful in understanding elevator problems if you need clarification. These types of problems are easy to solve using the techniques that we've already been using including drawing free body diagrams and writing Ξ£F statements. Remember, a bathroom scale will read your "apparent weight" or the NORMAL force!

Presentation: Elevator Problem

Homework: Finish Big Newton's Law Packet page 3 #1-5 (skip #1b) (SOLUTIONS to p 3 of Packet). If you need additional support on elevator problems, watch the videos below! Quiz on Newton's 2nd Law problems (including elevator problems) next class - Friday, November 19th!

### π 6: Th 11/18, π 8: W 11/17 - βPP Newton's 2nd Law problems

Today, we'll practice using ideas of Newton's Second Law in β Positive Physics from unit 5: introduction to forces:

• complete problems 1

• complete problems 2

• complete problems 3

• complete problems 4

Then, we'll continue working collaboratively in groups applying Newton's Second Law in problems:

• Elevator problems - Big Newton's Law Packet page 3 #1-5 (SOLUTIONS to p 3 of Packet). These types of problems are easy to solve using the techniques that we've already been using including drawing free body diagrams and writing Ξ£F statements. Remember, a bathroom scale will read your "apparent weight" or the NORMAL force! (These problems are not being collected, but you should do them to prepare for the quiz.)

• Find additional problems from Chapter 4 in the textbook.

Homework: Finish β Positive Physics problems in unit 5 by Thursday, November 18th at 10pm. Only completion score will count, so you can continue to try if you get it wrong the first time. Try to finish these problems early in case you run into technical difficulty. No late credit. Quiz on Newton's 2nd Law problems (including elevator problems) next class - Friday, November 19th!
