## 2nd Quarter: November 7 - 11

## Wednesday, November 9

**1st Period: Today in class…**

- Today we started out looking over our tests on Projectile Motion. Corrections on the test can be done, but need to be completed by next Tuesday.
- Afterwards, we had two very interesting presentations from Sana and Liana - great work ladies!
- As we started back with forces, we looked at equilibrium vs non-equilibrium as well as the vector nature of forces. Forces must be added by components - x's with x's and y's with y's.
- We did class examples 2 - 4 to get some practice with this idea.

**HOMEWORK:**Starting with Forces

Read in text (if you haven't already done so) Chapter 6, Section 1

**6th Period: Today in class….**

- Today we started with presentations from Bryce and Carlos (great job guys!).
- Afterwards, we reviewed what we know about Newton's Laws and saw some examples of them through the clip from Apollo 13.
- We then started working more with our 'speciality forces.' These are forces that are a bit more specific and have a specific name and formula.
- So far we've discussed the force of gravity as well as the difference between mass and weight.
- Afterwards, we learned how to draw Free Body Diagrams (FBD) and how the normal force can be used out of surfaces.
- As a thought to end class, we considered what bathroom scales
*actually*measure. More on this next time.

**HOMEWORK:**Read in text, Chapter 6, Section 2, ending on p. 134

**1st Period: Today in class….**

- Today we started with a presentation from Nikita. Great job and very interesting!
- After a quick review, looked more at Newton's Third law both with our demonstration in the back of the lab and from the scene from Apollo 13.
- We then started working more with our 'speciality forces.' These are forces that are a bit more specific and have a specific name and formula.
- So far we've discussed the force of gravity as well as the difference between mass and weight.
