For the 9 of you who actually downloaded and attempted the homework, I appreciate your diligence. Here are some resources for you.
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
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.
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.
Force is in Newtons
Charge is in Coulombs
Electric Field strength is in Newtons per Coulomb (N/C)
If you need help, email me!
If you wrap up early, get some work in on the wiki!
The program that you’re writing will be graded on it’s ability to do the follow.
- Questions that you should ask the user.
- Ask for Velocity Initial
- Ask for launch angle
- Ask for launch height
- Display the following:
- Component velocities
Vix and Viy
- Time the projectile hits the ground
Bonus points if you can eliminate the negative time!
- The distance the projectile travels
- Style points for:
- Using human readable variables
- Commenting your code
This project is due on Nov 25.
Read the requirements here.
There are instructions on how to turn the program into me in that folder.
If you would like to test your program, you can copy and paste it to http://repl.it/languages/Python
Please follow the instructions for our rotation lab here. Log into google drive, open the document, copy it into your drive, and save it in the folder that you shared with me.
Today we will complete a lab using PhET’s online simulation for springs.
Follow the instructions you find here, and complete the lab. This is a public copy from my google drive. You can’t edit it. Make a copy for yourself, place it in your google drive folder, and call it “Lab 9 Springs.”
There has been a lot of debate recently about the necessity of homework and it’s effect on grades and comprehension. I’m still open to discussion.
Here are a few articles discussing homework and how useful it really is. Feel free to find other articles and make your case. DO NOT use personal experience, feelings, or anything else that doesn’t have numbers.
Period 1 and 4. Please watch the following video about drawing free body diagrams. We covered most of this last week, but this is a good refresher, and actually takes the process a few steps beyond what we did.
Use this information to complete Force pt. 2 on WebAssign. It is due tonight at 11:59pm. If you have questions, please submit them through the site and I will try to answer them through the day.
There are now 3 assignments about 2D Kinematics on WebAssign. 2 were due previously. 1 is new. They are all due Today!
Over the weekend, I recorded 4 videos that might help you solve some of these problems. Watch them in small groups, and see if you can’t make some progress. As always, I’ll be near my phone and will try to answer questions on web assign, but I can’t guarantee how fast that will be.
Finding Component Velocities
Finding the maximum height of a projectile
The Water Balloon Fight
The Range Equation (use only on level fields Yf=Yi)
All: There is webassign homework due tonight on 2D Kinematics.
4th period: We recorded this morning’s lecture and posted it to youtube. As a class, watch the recording of the lecture. Once you are finished, work on the related webassign problems. Feel free to refer back to the video for help, (or look at the 2D kinematics section of OpenStax Physics. There’s a link in your class tab.)
