Hooke’s Law Lab

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.

Assignments for 9/15

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.

Assignments for 9/2

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)

Assignments for 8/25

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.)

Assignments for 8/21

The internet is back and the storms are gone!

Please finish your web assign assignments from yesterday.  It is all due tonight.

If you are finished, please open the lunar lander simulator on the PHeT website.  Once you have played around with it for a few minutes, go to google drive and try to write a control manual for flying the craft.  Talk about momentum!  Why does the craft “drift?” How do you compensate? What forces are at work on the craft?

Enjoy your weekend, the pep rally, and tonight’s football game.

Periods 1 and 4
