# Welcome to Spring 2015

Please tell me a little more about yourself by filling out my new student questionnaire.

Once you’re done, go to your class tab and look around! If you like to use remind 101 (I send you text messages about upcoming assignments, but your phone number stays private, and so does mine!) sign up.

Each class tab has a copy of the syllabus, and summary of topics that we will cover this semester.

# Circuit Lab 2

Today we will use the Circuit Construction Kit to investigate Kirchoff’s Law.  Please make a copy of the lab, and place it in your google drive folder for grading.

# 12/2 Circuit Lab

Today we will investigate the effect of voltage on a circuit.  Please complete the Phet DC Circuit Lab using the PhET Circuit Construction Kit.  Please write your answers on a separate sheet of paper to turn in.

# 11/21 Fourth Period

Thank you all for working so hard on the assignment yesterday.  There’s a new, similar assignment today.  Only 3 problems, but much more difficult (and worth considerably more points.)

Some hints for today:

First μ is a prefix meaning micro, or 10^-6.  So when you see 5.7μC, we’re talking about 5.7*10^-6 coulombs

Second, remember all of your rules about vectors, vector addition, and how to combine vectors from 2 dimensions into 1.

A really helpful tool: Hyper Physics Coulomb Force Calculator

For an Electric Field calculation, Q2 is usually just a single electron, or a single proton.  Use the calculator above, then divide the answer you get by the charge of that single electron.

First period:

For the 9 of you who actually downloaded and attempted the homework, I appreciate your diligence.  Here are some resources for you.

# Assignments for 11/20

Today is an easy day! You have webassign about electric force and electric fields. Try this without yahoo answers. If you need help Google “hyper physics.” It’s a great resource from the University of Georgia.

REMEMBER!
Force is in Newtons
Charge is in Coulombs
Electric Field strength is in Newtons per Coulomb (N/C)

If you wrap up early, get some work in on the wiki!

# STEM Python Project

The program that you’re writing will be graded on it’s ability to do the follow.

1. Questions that you should ask the user.
2. Display the following:
1. Component velocities
Vix and Viy
2. Time the projectile hits the ground
Bonus points if you can eliminate the negative time!
3. The distance the projectile travels
3. Style points for:

This project is due on Nov 25.
