 Happy St. Patrick's Day

Today we finished off the notes for chapter 5 lesson 2. We discussed the law of conservation of energy and how it is the same as the First Law of Thermodynamics.   

We then discussed how friction affects moving systems. We know that friction is a force that resists the sliding of two surfaces that are touching. We also discussed that to reduce the amount of friction, a lubricant such as oil, grease, or graphite can be used.   

We went on to discuss how all energy types can change from one form to another. 

Here are the notes.
