Have a safe & happy holiday break. After the break we will finish the forces unit and prepare for the final (primarily focused on forces, but some questions from kinematics may appear as well.) I will post a study guide in the next few days.

Santa Paws dropped in to 3rd period! When you are finished with the investigation you will be writing a conclusion to summarize what you know about friction. You need to identify 3 claims (conclusions) about friction, and support them with evidence from your lab and reasoning (how does the evidence support your claim). •Claim #1 statement. Evidence that supports claim #1. Reasoning that explains how the evidence supports your claim. •Claim #2 statement. Evidence that supports claim #2. Reasoning that explains how the evidence supports your claim. •Claim #3 statement. Evidence that supports claim #3. Reasoning that explains how the evidence supports your claim. Attach your C,E,R to your investigation packet and hand in. This is a lab grade! Today we continued working through the friction investigation.
Today we began an investigation on friction. We will continue working through the lab tomorrow.
So far in this unit we have covered the following topics (slides are linked to each topic). You can read about these concepts in your book in CHapter 4.
Forces and Free Body Diagrams (including Newton's First Law) Newton's Second Law Newton's 3rd Law Newton's Law of Universal Gravitation (gravity, mass, & weight) Normal Force Today we talked about normal force. You have a worksheet to complete for homework. Today we practiced using Newton's Law of Universal Gravitation to calculate the gravitational force between two objects. No homework tonight.
Today we talked about gravitational force, and calculated how much force one student exerts on another student.
Today we worked on practice problems using Newton's laws. Everyone finished the work in class - no homework.
Today we introduced Newton's 3rd Law, but did not get to do any practice problems...
