10/31 Physics update and homework due 11/7

Hi folks, 

Today we began our venture into Newton's Laws. To be honest, everything we've been working with so far has led up to this. Velocity, acceleration, vectors, linear motion has all been leading up to us gaining a strong understanding of Newton's three laws of motion. Today we began with Newton's first law, an object in motion stays in motion and an object at rest stays at rest unless a force acts against them.  

Homework for this week is to: 

Read pgs. 43-55 
Review Questions pg. 56 & 57 #'s 1-20

Also, do the enclosed .pdf.  It will help you get more practice on those pesky "river" problems.  Answers are included.

10/24 Physics update and homework due 10/31

Hi folks,

Today we took a deeper look at vectors and vector math.

We also did a fairly mathematically intense lab where the students had to find velocities and accelerations of a lego catapult.

For homework this week:

If you haven't already, finish the lab we did today in class. I need to see the:
Horizontal Velocity
Vertical Velocity
Resultant Velocity
Horizontal Acceleration
Vertical Acceleration
Resultant Acc

Time of the throw is .1 seconds.

10/17 Physics update and homework due 10/24

Hi folks,

Today we spent a bunch of time going over the formulas and doing problems to get the hang of the math that's associated with the topics we've been covering so far.

Homework for this week is to:

Read pgs. 28 - 39 in the text book.
Do "Plug and Chug" questions on page 41 #'s 1-5

We haven't gone over vector math yet in class but give it a shot. We will spend more time on it next week.

Do all 6 of the "Think and Solve" questions on page 42 of the Conceptual Physics book.

Part 1

Part 2

10/10 Physics update and homework due 10/17

Hi folks,

Today we spent a bit more time with a few more gravity concepts and we also touched on our next topic, projectile motion.

Here are links to the videos we watched in class.

Ball and cart Link

Horizontal vs. Vertical Link

Homework due next week:

Read the text book from page 10 - 24

Review questions page 26 #'s 15 - 25

Do Plug and Chug on page 26-27 #'s 1-8

Revised answer sheet for homework this week

Hi folks,
I notice a mistake on the answer sheet. Here is the corrected sheet.

10/3 Physics class update and homework due 10/10

Hi folks,

Today we spent some time working with a few formulas. All of which will be used quite a bit as we moved forward.

We also discussed many concepts surrounding gravity and will do more with that next week.

Homework due next week is to do the enclosed .pdf.

I've included the answers so that you can make sure you're on the right track.
