T 1/16

W 1/17

Th 1/18

🟢❗ 5: F 1/12 - work by non-conservative forces

Pendulum Lab assessment TODAY!  

Today, we will look at some problems where we can use our knowledge of kinetic and gravitational potential energy to solve complex kinematics problems with friction. Conservation of energy is a useful tool and a alternative to using Newton's Laws and kinematics. Remember that work and energy are scalar quantities.

With time remaining, start the 📖 Mastering Physics problems "Ch 10 - energy conservation" #35, 37, 39, 42, 43, 47, 49, 79. 

Presentation:  Conservation of Energy Examples  (we'll focus on the last two slides)

Optional Extra Practice: Work & Energy Packet page 4 #1-5 (Solutions to FYP: Energy). 

Homework:  Review your notes and write down any questions you have.  Try some of the optional extra practice.  Consider starting 📖 Mastering Physics from next post to get ahead. Quiz on energy conservation problems on Monday, January 22nd.  

🟩 5: T 1/16 - 🌨️❄️☃️ SNOW DAY! ☃️❄️🌨️

💚 5: Th 1/18 - 📖 Mastering Physics energy conservation

Today, we'll start with a discussion about Energy Bar Charts.  This is an option if you prefer these to Before & After Diagrams.  

Then, we'll practice all we've learned about work and energy by doing 📖 Mastering Physics problems "Ch 10 - energy conservation" #35, 37, 39, 42, 43, 47, 49, 79. 

Homework:  Finish these 📖 Mastering Physics problems by Friday, January 19th at 10pm.  Quiz on energy conservation problems on Monday, January 22nd.  

Optional Extra Practice:  so far...
