AI Assisted Argumentation
The user will be presented with a physics problem and the AI is given a system prompt to guide the user by asking socratic questions. This is a simulated interaction based on my user input (not a student's), but with actual responses from the AI assistant.

Editing the GeoGebra LOL Diagram Template
Переглядів 549 місяців тому
Modify the LOL diagram according to the Physics problem you are trying to represent from www.geogebra.org/m/u2m3gnzj. 1. Make a copy of the GeoGebra app. 2. Edit or delete any parts that you want to change. 3. Check that the energy bars are balanced.
Centrifuge Toy
Переглядів 345Рік тому
I designed this in Tinkercad and printed using the Creality Ender 3. This toy is used to demonstrate the centrifuge's working principle, where objects being spun around tend to spiral outward if there is insufficient force acting as centripetal force to keep them in circular motion.

Bulbs in Parallel
Переглядів 1,7 тис.3 роки тому
Notice what happens when a bulb is removed from its socket. Based on the assumption that the potential difference across the light bulbs do not change, the brightness of the remaining bulbs should remain the same. However, they do not! Can you explain why? Leave your answers in the comments below.

Using a Potentiometer to Measure Small Emfs
i don't think this is shielding, more like "shorting"
music too loud for voice. Rest: thank you.
Can i get the stl files somewhere?

Interesting
Would an epoxy coating on the copper metal sheet effect the magnetic braking?
but wouldnt the induced steel become an induced magnet and attract the paperclip
is it the nickel content thats interfering with the magnetic field?
Like the experiment setup - simple and very practical to play around cheaply - well done!
Word.
Bulbs had diff resistance ....if all of them had same resistance they would have same brightness
But how
It would be helpful without background music
Haha that one headphone user at the bottom staring at the structure. If that whole thing drops, he won't have time to react, because he can't hear its descent through the air. The perils of being a headphone user.
BUNZ... BUNZZZ. BUNZ... BUNZZZ.
A bit quick, faster than the time it took those light bulbs to transmit light, haha
Wth, this circuit video is so useful, how did I never see this befoe?
THE current Is being divided by 3
Not exactly. For an ideal battery, the current through each light bulb will not change so its brightness should not decrease. But nothing is ideal in this world. We need to consider the internal resistance of the battery which causes the potential difference across the bulbs to drop. With more light bulbs in parallel, the effective external resistance decreases even further.
@@PhysicsLens Oh, thank you for the explanation. I got it.
It is due to the increased resistance provided by the extra length of wire when the more bulbs are connected.
epic
WHY????
i did this test right now with my sunglasses and the exact thing happened
I can’t take it seriously since the music
Going up bc the pull force of gravity on a elevator going up is higher and going down is lower
Goin sideways
This pendulum consists of a strong magnet. If we slide a copper plate underneath the magnet while it is in motion, the magnet comes to a stop quickly. ... As the magnet moves across an area on the copper plate, the change in magnetic flux induces eddy currents on the plate.
Burning half a coin neodymium magnet also causes it to never again attract magnetic metals, however, will become a South Pole next to the North Pole.
He is stuck in the elevator for sure
I havent heard this music in a VERY long time
This is exactly what I need you are the best
What is that?
Wow your clock is better than mine i upload my clock in my channel but you are so cool
Can I use this video at my channel.I will attach the link
Sure. Please go ahead.
I did . thank you
Great demo. Is that a voice to text app for the narration? If so, which? Thnx
So will ferritic steel and nickel plated steel also prevent the magnet from being attracted to other magnets?
Yes they will.
@@PhysicsLens good, so long as the material used to perform shielding since I found nickel chromium is another material.
fire my guy
lit
lit
Thank you, now I can stop afraid make magnetic fluid electricity generator!
I gues i rebuilt thismfor my sci experiment and won first place it took me over 30 hours to make this and itnis worth it
At 0:28 it says this ferritic steel is a “Book End”. I don’t suppose anyone knows what specific bookend and brand this is, or where I could find the same type? I’ve tried this experiment with other bookends and some stainless steel, but it doesn’t seem to work as well.
Poor video, no clear data
u
Что за материал
УРАН 235 !
Ditto the comment of the guy before mine. This makes no sense!
So here’s a video that purports to show how to use a tuning fork, but the demonstration is utterly obscured by distracting and irrelevant music.
Nice
What music
From iMovie
Fuckin tune that
wow toll
The music is really annoying
The Metal Hunter yeah i get suicide thoughts from it
Great sir thanks
It deflects the field, not shields from it. Maxwell's laws still apply, even with the ferrous alloy bookend. Magnetic fields can't be blocked.
Which is best and cheap material for diverting magnetic field?
I think aliens could say a thing or two about it. They had space ships 1000s of years ago so they know better.
Whatever gets it done. Do you know any other deflecting metals?
Yes try puttin copper in front of it and will still magnetize
