🟢 8: T 9/30 - 📖 freefall problems
Today, we'll start class by debriefing the freefall lab. As a class, we'll discuss the findings of the labs and the understandings that you should now have about freefall. We'll gain the understanding that freefall is just a special case of constant accelerated motion where the acceleration is g = 9.8 m/s² downward. We'll talk about notational differences between freefall problems and other more general kinematics problems (acceleration notated as g, and using Δy instead of Δx).
Finally, with any remaining time, we'll start on some freefall problems from the textbook 📖Chapter 2 #46-52 & 55. Make sure to still follow the protocol for writing out your solutions:
Draw a picture or diagram or graph.
Pick a sign convention.
List your knowns and unknowns.
Write the formula you'll be using.
Rearrange the formula with algebra so that your unknown is on the left side of the equals and all the knowns are on the right. STAY IN VARIABLES!
Plug in numbers and box your answer. UNITS ON ALL NUMBERS!!!
Homework: Quiz on Kinematics Problem Solving on Wednesday, October 1st (does not include freefall). Finish 📖 Mastering Physics Ch 2 problems by tonight - Tuesday, September 30th. Because I reopened it, students who already finished it may do it again if you lost points anywhere.

⭐OPTIONAL GRADE INSURANCE⭐
⭐OPTIONAL GRADE INSURANCE⭐
We are offering optional "grade insurance" for this unit. Grade insurance gives you the opportunity to mitigate lower grades by doing an extra assignment.
Our grade insurance for this unit is an optional lab in ↩️ Pivot Interactives called "Free Fall Five: Advanced Introduction to Motion in Free Fall." I recommend this activity for anyone looking to understand freefall a bit better and to improve your grade. To access the assignment, go to Pivot Interactives from your ClassLink. The due date for the lab is Monday, October 6th at 10:00pm. You may submit as many times as you like before the due date and time, so there is no reason to get any less than 100% if you choose to do this activity.
The grading for this optional activity will be out of 10 points in the "Assessments/Labs/Projects" category. ABSOLUTELY NO LATE WORK WILL BE ACCEPTED FOR GRADE INSURANCE!!!
