Both same

I know that fast air has lower pressure, but the principle about average velocities is not something I had considered as to WHY it’s lower pressure. Less collisions to transfer momentum perpendicular to the flow. Neat!

Cool and good 👍

Thanks.... I thought the paper lifts up because of a density difference. But it is not the real case. Now i know...😮

Modern tv remotes also work like that , but with a IR light wave that is switched on and off at 40 khz which makes an electronic circuit resonate and detect (demodulate) the signal.

Ultrasound resonating at the frequency of concrete .is it used as weapon to destroy buildings?

. You're not even half done... now demonstrate the reaction when you use harmonic intervals above V.S. below the natural frequency of the passive tuning fork and the cumulative effect of multiples harmonic tones spaced out at... Sorry I get carried away. Thanks for the further explanation of the sonic clicker by the way. I never got to disassemble one of those apart to see exactly how it "hears" the sound and activates the relay. Not sure why the TV repair guy thought he couldn't explain it to me just because I was 6. I was already using the Thomas organ to "ring" the strings on the Guild. .

Thank you.

Are the vibrations passed through the air or the wood that was touched? When did those TV remotes exist, the 60s and early 70s?

We need more teachers like you. Hands on physics will get so much more attention from the students. And is also so much easier to remember.

Vibrations

Equal everywhere because tension want to maintain length

Interested short leacture, I really appreciated

Al-Bayruni calculated it

Can it play fein?

It isn't flint. Its an alloy made from cerium and iron. Smal particle of cerium brake off and ignite.

Buns and birds? Didn't you mean Bunsen burners?

WHERE ARE THE FULL VIDEOS IVE FOLLOWED THIS GUY FOR OVER A YEAR AND I DONT UNDERSTAND

it's not flint, it's ferrocerium

That’s very cool 👌

Any idea how long it generally takes one of these to wear out? My chemistry class had one that almost never gave a single spark

That is an awesome device for starting fire !

lagrangian mechanics in the back 👀

Very good demonstration 😇

Im here because A certain magical index season 1 ep 13

How does this work and why does this occur? Is there a name for this experiment?

The non intuitive one is when you keep the wheel vertical but move it 90 deg.

The momentum of inertia needs to be preserved. The wheel rotates in the opposite direction. So, your speed of rotation needs to increase to keep the same momentum of intertia.

Everyone hates it, when will this madness end?

loved it

It’s saving some of us from having accidents because we can’t drive safely in the dark.

Thanks for the clear explanation and demo.

The sum of the forces is equal to change in mass times velocity plus change in velocity times mass?

You'll get an initial reaction in the opposite direction but nothing more because the wheel spinning isnt producing any torque.

🤯

I'd assume the reason the forces aren't exactly the same is because the putty on one squished more than the other, displacing a small amount of force away from the sensor?

Part 2 huh? Home I come across it one day

One newton, the car isn’t decelerating by that much cause the mass of the bug is insignificant

i'm stupid, but still not get it (why I can't see the dark side of the moon)

Trick question. We killed off all the bugs with industrial strength pesticides.

Less than 1 Newton

Radius Of Curvature vs Curvature

I would say equal. Action = reaction when 2 surfaces are in contact.

Here because I'm a pyromaniac

Bruh, it cut off..

What savings? Does your electric bill goes down? BS

This made no sense , thanks a lot

Need to use newton's third law to explain direction of force on scale.
