Unit 3- Dynamics

Unit Three – Dynamics
Goals
1. Draw Force Vectors.
2. Calculate Weight.
3. Solve Problems with Net Force.
4. Know that when an object is at rest or moving with constant velocity that Fnet = 0 and all of the forces are balanced.
5. Understand what terminal velocity is and how it is reached.
6. Be able to explain why all objects in freefall have an acceleration of 9.8 m/s2
7. Understand that forces are interactions between two things and that each object exerts an equal and opposite force on the other.
8. Know Newton’s Three Laws of Motion by name.
In general, understand Newton’s 3 laws and apply them to explain motion.

Checking Grades

Here is a link to the Parent Assist website.

Many Grant teachers will use this district provided program to maintain and post their grades. You will also be able to monitor attendance and check personal information. I will update grades after every major test and lab, but I might not get every late assignment or retake in the gradebook promptly.
To use this website you will need to get a personal code from the Grant High School office. If you have a code from last year or for any other child it should still be active.

Installing Logger Pro on your Home Computer

As a Grant High School student, you have access rights to our site license for Logger Pro. When you graduate, you should uninstall this program.

To download it to your home computer requires several steps:

1. Go to the PPS Virtual Office Webpage, which allows you to access your student X drive remotely.
https://files.pps.k12.or.us/vo/servlet/portal?render=on

Use your PPS log in: initials and student ID.
(This link is also on the Grant Web Page, a handy feature for transferring files to school.)

2. Download the Logger Pro installer.

To get to the installer first choose the NETSTORAGE icon on the right. Then Choose DriveX@Dept, followed by Student Files, and finally Logger Pro 3. It's a big file. You might not want to try this if you're still using dial-up.

3. "Unzip" the installer. The file is large and compressed. Your computer may do this automatically, or you may need to download a program to do this. Here is a link to a free utility to do this. http://www.7-zip.org/

Once the folder is open, you want the SETUP application - not the setup bitmap, or document, etc.

Good Luck with this let me know if it doesn't work.
