Unit 1
Unit 1: Kinematics in 1 Dimension
Goals:
1. Know and apply the definition for average velocity.
2. Know and apply the definition for average acceleration.
3. Differentiate instantaneous and average velocity.
4. Interpret graphs of position, velocity and acceleration, including through the use of slopes and the area under the graph.
5. Draw position, velocity and acceleration graphs for described motion.
6. Know the acceleration due to gravity.
7. Solve problems by using 5 basic mechanics equations.
8. Properly use sign conventions for positive and negative acclerations and velocities.
9. Describe sources of error as either random or systematic and suggest basic ways of reducing error such as controlling variables, doing multiple trials, collecting data over a wide range and using big sample sizes.

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. The secretaries expect to receive these codes soon, but have not received them yet. I will update this post when they are available. If you have a code from last year or for any other child it should still be active.

Welcome Back & General Information
The 2008-2009 school year has started. Welcome to Physics.
Here is some general information about how the class runs.
Grades:
Approximately 50% Tests, 30% Labs, 20% homework
Tests: About twice a quarter, with semester finals also. Retakes are available, but only half the missed points are recoverable.
Labs: Although we’ll have weekly hands-on lab assignments, I’ll only have you write up formal lab reports about twice a quarter. (The first one will be due Sept. 15.) Late labs are penalized at 10% a week.
Homework: I’ll check them off for effort and completion on the due date and collect them in a packet on the test day. Show your work, be neat, stay organized. Talk to me if homework ever feels like busy work. No late homework accepted except for excused absences.
Grading Scale: 100-90 A, 90-80 B, 80-70 C, 70-60 D, <60 F.
Supplies:
Textbook
Notebook, or section of a notebook
Calculator
Protractor
Graph Paper
