Free-body diagrams this week in Physical Science (test on Friday!)

This week in Physical Science we will introduce the concept of free-body diagrams, an absolutely critical concept in the study of the forces acting on a system and how they will affect its motion. With the upcoming test on Friday, this week will be more focused on polishing the concepts of Newton’s Laws and forces already introduced; Thursday will be solely dedicated to answering students’ questions about the test the following day.

The following extra-credit question will appear on the test:

What are the three types of adult bees in Mr. Willco’s hives?

Students are of course welcome to study together if it will benefit their understanding of the material, but I ask that they not share this question with each other; they may absolutely share with their classmates that an extra-credit question is posted on the blog, but I want students to look up the information themselves.
