11/30 Physics class update and homework due 12/7

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

11/15 HS Physics update and homework due 11/30

Hi folks,

First off, NO CLASS next week. Enjoy the Thanksgiving holiday everyone!

Also, be sure all homework is turned in when we get back together after Thanksgiving. Feel free to email me if you're not sure if you are missing any assignments.

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.

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.

11/9 Physics update and homework due 11/16

Hi folks,

Today we spent a good amount of time diving deeper into the many aspects of Newton's Second Law.

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

11/2 Physics Recording - Newton's Second Law

11/2 HS Physics class and homework due 11/9

Hi folks,

Today we had a quite a bit of fun getting hands-on with Newton's Second Law.  We even got a chance to enjoy the nice day by using a wagon to explore the law.

For homework, use the data that we took today (see below) to determine the force applied for 4 different students.  (Be sure to convert pound to kilograms. (Google can be your friend for this.)  Use the formula f=ma to calculate force.  Also, using the data for one person, create an acceleration vs. mass graph showing all three different masses.  

For homework, I'd like you to go to this webpage and use it to finish the enclosed .pdf.  (Don't worry about #15.)
