### 🟢❗ 5: T 10/24 - Newton's Second Law continued

Closed-notebook lab quiz TODAY.

Today we'll continue to learn how to use our free-body diagrams to solve problems using Newton's Second Law.

In addition, we'll talk about the results of the lab and learn about what the accepted value is for our constant.

With any time remaining, we'll work through homework problems or start 📖 Mastering Physics problems from the next post.

PresentationHow to use Newton's Second Law

Optional SupportDo Simple Forces CompuSheets #1 (SOLUTIONS).  Then, do #1-2 in FYP: Newton's Laws of Motion (SOLUTIONS).

Homework:  Start on the 📖 Mastering Physics problems from the next post.  QUIZ on free body diagrams and basic Newton's 2nd Law Monday, October 30th!

### 🟩 5: W 10/25 - 📖✏️Newton's Second Law problems

Today, we'll apply Newton's Second Law by collaboratively on "Ch 4 - Newton's Second Law in 1-D (basic)" textbook problems in 📖 Mastering Physics#15, 17, 19, 20, 22, 24, 25, 34, 66; plus #7-10 on page 1 in  Newton's Second Law packetSOLUTIONS and upload your solutions to ✏️ Google Classroom.

Optional Extra Practice: all of  FYP: Newton's Laws of Motion (SOLUTIONS).

Homework:  Finish 📖 Mastering Physics problems by Thursday, October 26th at 10pm and #7-10 on  FYP: Newton's Laws of Motion (SOLUTIONS) and upload your solutions to ✏️ Google Classroom by Thursday, October 26th at 10pm QUIZ on free body diagrams and basic Newton's 2nd Law Monday, October 30th!

### 💚 5: F 10/27 - 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 Elevator Problems #1-5. (skip #1b) (SOLUTIONS). Watch the following videos 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 ΣF statements. Remember, a bathroom scale will read your "apparent weight" or the NORMAL force!

If we finish early, we'll start the problems from the next post.
