🟢 5: W 11/20 - 📖 textbook problems dynamics in 2-D

Today, we'll practice static equilibrium problems in two dimensions from the 📖 textbook chapter 5 #1-4, 7, 10, 34, 75.

Homework: Optionally finish 📖 textbook problems from chapter 5.  Quiz on static equilibrium & 2-D vector forces next class - Friday, November 22nd.  

🟩❗ 5: F 11/22 - inclined planes lab (1)

Quiz on static equilibrium & 2-D vector forces TODAY.  

After the quiz, we'll start to investigate the behavior of objects on an incline.  You'll take data to try to find a relationship between the magnitude of force that prevents an object from sliding down an incline and an angle of incline.  

Homework:  Please make sure to finish analyzing your data in your individual Google Sheet and fill out the Google Form.  This needs to be completed if you are to perform the next part of the lab next class.  

💚 5: M 11/25 - inclined planes lab (2)

Today, we'll continue the lab we started last lesson on inclined planes.  We'll assess our mathematical model from last time and take more data if needed.  We'll try to refine the mathematical model that shows the relationship between force and angle of incline.

Then, we’ll look at how we can apply what we know about vectors in two dimensions to inclined plane problems. The key to inclined plane problems is picking a coordinate system that makes sense.  We must shift our thinking from a traditional horizontal-vertical coordinate system to a slanted coordinate system.   We'll talk about what factors affect the motion of an object on an inclined plane theoretically and in real life.
