Today, we'll prepare for the unit assessment next class by going back and finishing any assigned problems that you haven't gotten to yet. Additional textbook problems are available to anyone who has finished everything. Or do something creative like write problems for each other!
Some ideas for you:
Finish Friction & Vector Forces (SOLUTIONS)
friction problems
inclined plane problems from textbook
static equilibrium problems
Homework: Study for Unit Assessment on Dynamics in Two Dimensions next class - Friday, December 5th!
🟩❗8: F 12/5 - dynamics in 2-D assessment
🟩❗8: F 12/5 - dynamics in 2-D assessment
Unit Assessment on Dynamics in Two Dimensions TODAY!
After the assessment, we'll start looking at the next topic of projectile motion. Do two ✅ Formatives:
#1 Projectile Motion Predictions
#2 Projectile Motion Prediction Graphs
Homework: Finish the two ✅ Formatives by 10pm tonight if you have not yet finished. Optionally make your own projectile motion video to use in class tomorrow!
Remember the following:
Find a background that is pretty much one color. Doing it in the hall or against a blackboard or whiteboard are all good options.
Record in .mp4 format (video settings = "most compatible" on iPhones).
Don't move your camera during the video.
Make sure the projectile never leaves the frame.
Have a meterstick in the frame at the same depth as the projectile for scale.)
Upload and share the video with your partner through your school Google Drive account. Double check that it's in MP4 format.
Here's an example:

Today, we’ll start looking at projectile motion. We’ll start by looking at projectiles launched horizontally. We’ll discover that projectiles move at constant velocity in the horizontal direction where there’s no net external force, whereas they move with constant acceleration (g) in the vertical direction where the external force is due to gravity. (Air resistance is ignored.) In order to solve projectile motion problems, we often split the problem into x- and y-components, and then combine x & y with time.
With any time remaining, you'll start looking at problem solving
Presentation: Projectile Motion
Homework: Quiz on projectile motion on Friday, December 12th. For more support, watch the following two videos by Dan Fullerton. They are both on projectile motion. Watch only the first 11 minutes of the first video, and watch the entire second video. The second video contains examples which you need to work through alongside Mr. Fullerton.
