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 📖 textbook problems from chapter 10 on 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.
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 continuing 📖 textbook problems from chapter 10 on energy conservation #35, 37, 39, 42, 43, 47, 49, 79.
Homework: Finish these 📖 textbook problems. Quiz on energy conservation problems on Friday, January 31st (marking period 2).
Optional Extra Practice: so far...

Today, we'll finish our unit on energy by defining power as the energy per time. After giving a couple of examples, we'll do 📖 textbook problems from chapter 10 on power #59, 61, 63, 65, 66, 69.
Then work on some extra practice below!
