Car suddenly turning into exit meme, with car labeled “car moving at constant speed” straight labeled sigma F = 0, and exit ramp labeled sigma F = mv^2/r
Favorite memes to explain stuff?

A colleague (non-science guy!) sent this curling physics article to me. Lots of good stuff! Mentions tribology by name. Mentions the earliest known hypothesis and a bunch of competing present-day ones. #ITeachPhysics

This is my usual viewing too - one of the best physics videos in my opinion! I like how it discusses fictitious forces in linearly accelerated frames first.
Fantastic, thank you for this!
I like this animation first: youtu.be/1_UBPOiNHj8?...
Oh these are absolutely fantastic! Thank you for sharing!
Physics teachers, how do (if at all!) explain the centrifugal force?
I am interested in this tricky bit of physics and keen to hear your ideas!
#iteachphysics
Will look for this, thanks!
Nice. I like your use of 'zoom out' in the context of FoR. You introduce centrifugal force as a fictitious force acting on the object then, as opposed to the reaction force on the agent of the centripetal force?
Great read - always a big fan of summation notation for resultant force!
Great read thanks Joe! Out of interest, do you mention the centrifugal force to students? If so, how do you explain? 😊
The front cover of the book: Crick, by Matthew Cobb
Loved this brilliant biography of Crick by @matthewcobb.bsky.social But what struck me from the start: it's also a portrait of a lost time in science: no grant applications or teaching, big travel budgets: the job only to think, talk & get science done. Future scientific biogs will be so different.
Thanks for sharing, that will make a great starter question for my a-level projectile motion lesson :) #iteachphysics
When I have set a class questions to complete independently, I spend around 10%-20% of the time at the start standing at the front of the classroom. Seemingly doing nothing.
I mentioned this to a colleague who asked "but shouldn't you be circulating?"
No. 🧵
Picture from Newtonian Physics for Babies, with two balls of different size. There are balanced up and down forces on them. Below it says “The force of the ground always equals the force of gravity”
Not when I throw the book on the ground in disgust #iTeachPhysics
A photograph showing four digital thermometers. They are reading 21.8, 21.6, 21.4, and 23.2. All in degrees C.
So. What is the lab temperature?

Some say it looks boring, but for me it makes it standardised and easy to manage as it’s all code! Also in the age of Copilot, editors understand code better.
Here’s my frequently used LaTeX packages to make my worksheets.

What will happen to the balance reading when I drop a magnet through the copper pipe which is supported on a clamp stand on the zeroed balance? A predict and explain demonstration with electromagnetic induction, terminal velocity & Newton 3

New blog post!! I wanted to share the mini lab set up that I used to introduce mathematical models in my physics classes. I'm especially proud of the inverse square relationship comparing the diameter and length of a playdough snake 😊 #iteachphysics

Sourdough starter in a Weck jar maybe one fifth full with a printed label that reads, "Sir Isaac Gluten"
Gonna tell my students this is the name of my sourdough starter

I have a new article out in the Chartered College of Teaching journal Impact, called ‘Embedding AI in education: A critique’. Here I make five main points, which I will helpfully plop in this thread for those without access or time to read it.

Big big fan of this. Lots of thought provoking stuff. Have unfortunately worked in a 'rocket ship' school and am very glad to be out!
