12/17 Physics Recording - Free Body Diagrams

12/17 Physics class and homework due 1/6

Hi folks,

First off, happy holidays everyone!!!!  I hope all your events are wonderful, warm and safe.

In class today, we got into a new concept of free body diagrams. Free body diagrams help to analyze the different forces on objects in order to determine the net force and acceleration of those objects.

I'm taking us a little deeper than the book goes on this subject so homework this week is to read the following web pages

http://www.physicsclassroom.com/class/newtlaws/Lesson-2/Drawing-Free-Body-Diagrams

http://www.physicsclassroom.com/class/newtlaws/Lesson-2/Determining-the-Net-Force

I would highly recommend taking a look at the problems and the solutions on each one of these pages.

Also, do the interactives on this page http://www.physicsclassroom.com/Physics-Interactives/Newtons-Laws/Free-Body-Diagrams/Free-Body-Diagram-Interactive. The page is a little clumsy, but with a bit of patience hopefully you'll get the hang of it. When you get the answer, write down the force body diagram on a separate piece of paper to hand in.

See you all in 2019!!!

Outside a bit for Physics today

Hi folks,

If we have time, I'd like to spend a little of it outside today so please dress ready to be outside for about 20 minutes or so.

See you soon!

Best,

Physics Class is Cancelled for tomorrow

Hi folks,

I hate to say this but with today's snow and the prediction of freezing rain tomorrow I think it's best if we cancel class.  

Stay safe and warm everyone!

12/3 Physics Class Newton's Second Law

Part 1  https://youtu.be/iHdYONfvjQc

Part 2 https://youtu.be/AIanmTN3WBY

12/3 Physics Class and homework due 12/10

Hi folks,

We spent some more time getting to know Newton's Second Law today. To "get our hands on" the concept we went outside and saw how Newton's second law applied to pulling a wagon. We put more and more mass into the wagon (0, 1 and 2 students) and saw that as we increased the mass the acceleration went down.

Homework due next week is:

Read pages 59 - 70 in the text book



Do Review Questions 1 - 18 on page 71 and 72

Do Plug and Chug questions 1 - 5 on page 72

Physics Class

Hi folks,

We are going to be doing some stuff outside for physics class so please dress appropriately. 

Best,
