12/5 Physics Class Recording - Momentum

https://youtu.be/Tyz_4Eac3zw

12/5 Physics update and homework due 12/12

Hi folks,


Today we spent a little bit more time with free body diagrams as a review and then we moved onto the new concept of momentum. Momentum is basically how hard it is to get an object to come to a stop or to change directions. Mathematically it's mass times velocity. We took advantage of this beautiful day by doing our lab outside. The lab was seeing the effect of different masses and different velocities on momentum.


Homework due next week is :


Do the Momentum vs. distance the block moved graph.


Also,

Read pgs. 74 - 82

Do Review Questions #'s 1 - 18

Recording of 11/28 Physics Class - Free body diagrams and Newton's 3rd Law

https://youtu.be/kEBPtH96cKw

11/28 Physics class and homework due 12/5

Hi folks,


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.

We also spent a good bit of time learning Newton's 3rd Law and demonstrating how it works with the help of two skateboards.


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.

Please bring a coat to Physics Class!

Hi folks,

I'm planning on doing some stuff outside today so please bring some warm clothes since it's going to be pretty chilly today.

See you all soon!
