1 PreQuiz/Skill Set
6.1 – Work and Energy
Homework from 7 nights
Test on Energy and circular motion – you will need to study for this. Check on the website – I will tell you the problems to study. You will need to review the circular motion questions.

[1] Please start each night’s homework at the top of a new page, and number each day 1, 2, 3…etc. Put the solutions to the energy sheet with that day’s homework. This will make it easier to grade. If you are lost – look at it as a creative writing assignment – write about specifically what you don’t understand…
