🟢 5: W 12/4 - dynamics in 2-D review

Today, we'll make sure everyone has completed the ➕ Positive Physics corrections for the Unit 8 assessment.  Please make sure you've also changed your password in ➕ Positive Physics.

Then, 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)

• inclined plane problems from textbook

• static equilibrium problems

• pulley problems

... or if you feel like doing something different for the next unit, make your projectile motion video!  (If you're doing this, remember to be in .mp4 format, don't move your camera during the video, make sure the projectile never leaves the frame, and have a meterstick in the frame at the same depth as the projectile for scale.)  example video

💚 5: M 12/9 - projectile motion intro

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. 

Presentation: Projectile Motion

Homework:  Quiz on projectile motion on Thursday, 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.
