Physics First modeling workshop in the Philadelphia area! If you are in Southeast Pennsylvania, Delaware, or Central/Southern New Jersey, register now for a two-week Physics First workshop, June 17 - 28. https://t.co/7AQ26mJzuu #iteachphysics
@joel120193@ChatPhysics They should ask "Can it be one thing? Or does it need two?" Force always involves two objects: this pushes that. It can never just involve one thing. Energy can be just one thing: this object is hot/high up/moving.
@Prockwell4 Hmm... That circuit actually designed and built by my grad student, Denis Pelekhov, about 30 years ago. I don't think I ever knew the answer to your question. (That's the good thing about good grad students!)
@nickbakerqes@kilroi22 Sorry. Written to work on a chromebook. I think that writing stuff like this to work on both a laptop and a phone would require an actual software engineer instead of a high school physics teacher.
V5.7 of nPlot is out. Basics are the same, but now you can edit annotations, and saving a graph saves all curves plus annotation as a single file. Plus, it almost has a user manual. https://t.co/XmNSqzkaih (open to all, no ads, no tracking!) #iteachphysics
Teaching about oscillators and suddenly need my students to plot five force vs. distance graphs at once. So nPlot now supports 5 curves instead of 3. Free and available to all! https://t.co/XmNSqzjCsJ #iteachphysics#nPlot
@mrpauller Found notes for dropping a bare egg into a structure on the floor. If a first drop was successful, they try from the next height. Budget: it doesn't matter. Make sure they can "buy" enough to be successful if thoughtful. You are only trying to force them to make choices.
In class today:
Me: "1 noether = 1 kg m/s"
Student: "If I use noethers in college, will they think I am crazy?"
Me: "Yes."
Student: "Good."
#iteachphysics#noethers
@vincent_grgoire I'm leaning towards noe. We have a few other units with 3 letter symbols (think mol). Avoiding confusion with, say, newtons, seems worth the extra ink.
Teaching momentum again, and still bothered by no named unit. There are 19 SI units named for men, none for women. It is time for the noether! Equal to 1 kg m/s and named in honor of Emy Noether and her theorem. Hey #iteachphysics, how do we make this happen?
