Forces, Motion and Newton

Physics folks got an earful about Newton's first law of motion and a review of free-body diagrams. Remember that the force producing an observed acceleration is the net external force - sum up those vectors! Tomorrow, you will get to preview N2 and N3 in lab and we will take up the concepts in class on Thursday. Read the lab packets tonight to get an idea of what equipment you will be using, data you will be collecting and how to make your group work efficiently.

Honors Physics - coverage today of weight and the normal force with time to work on homework after the laws of motion quiz. A nice, easy day. Admitedly, half the people weren't here due to the field trip, but that was just butter on the bread. Tomorrow, we will go over the homework while the field trip slackers take their quiz and then move on into friction. The concepts of weight, the normal force and their resolution will take on large roles as we beging to calculate frictional forces acting on objects.

Physical Science - an entry into Newtonville with an overview of the first of his 3 laws of motion. We will work more with his 2nd law of motion in class tomorrow, espeically with the math portion. For those who did not score well on the math portion of their last test, stop in before or after school tomorrow to go over those pieces. You will need those skills as we move forward through this unit and through the course.

Addendum: I am losing my voice again, so everyone be prepared to listen closely and help out neighbors with work. Laughing at me is permitted, but be prepared to dodge a flying eraser...
