Changes to this week’s activities to make up for last week’s snow days: In lab this week you will do Chapter 1 Activities 5 and 6 AND Chapter 2 Activity 1, so, please read these text sections to be ready! Homework for Chapter 1 Activities 5 and 6 is due at the beginning of your lab session the following week. There is no Chapter 2 Activity 1 homework. We will do another “extra” activity in some future lab to get back in synch with the course schedule. I will let you know when to prepare for this. Notices: Please check CHIP to verify that your I-Clicker is properly registered and that your I-Clicker points for the last lecture have been recorded. You MUST register your I-Clicker by next Thursday afternoon to receive your points for last lecture and for this lecture. In-class test on Chapter 1 (25 minutes) next Monday!

Interactions and Energy Throughout Chapter 1 we have been developing ways to explain physical phenomena using energy ideas. Last week we discussed not only what we had learned about making such explanations but also the interesting way we extended the range of phenomena we could explain by introducing new kinds energy and new kinds of interactions between objects. For example, introducing the concept
