shes the safer one. NEVER wear gloves when using power tools. NEVER.
Or is she?
*Wish we had a science teacher like him, when we were in School*
We do he’s here now in the new age of school watch and learn
*The reason we are watching now is because of the dumb teachers we had.*
@@Maxim.Teleguz imagine being able to properly convey an idea, while in the process also teach? Sounds like a gift and unique ability. Don't be so harsh on your teachers.

If he were your teacher, he'd be teaching you the same lame shit you learn already, it wouldn't be any different. You'd be learning the equations behind this, not the theory. But sure, I get what you're saying.

In a parallel universe, gravity defies self correcting pendulums
Imagine you pooping upside down and your poop goes in space
The double pendulum glow paint (?) part at 4:32, combined with the music he switched to, made for a really cool segment.
At 3:00 has anyone else noticed yes the pendulum is inverted.... but he’s basically became the pendulum? And also shoulda probably covered isochronism in this video since it’s on pendulums
5:04 I'm confused... Was this a face of fear or enjoyment ?
Yes. 😂
Fenjoyement
4:33 holy crap, that's so amazing😮😎😎
It looks so cool with that uv light charging that glow in dark background😍😎😘
As usual, this channel does basic but surprising physics things I've seen nowhere else.
Show people the scene at 3:45, ask them to figure out what is going on.
At 4:00 seems like a good sword invention. Somehow.
When a pendulum is a better raver than you 😂

I love your new concepts!! Love from Nepal.. Cheers
Ok guys let's try one question. Suppose I have an ice floating in a beaker . But inside that ice there is an iron nail . So after melting that ice will the level of water in beaker.
a) increases
b) decreases
c) remains same.
Let's try this one.
Ha bhai ye youtuber bahut acccha hai i am from india
C
@@manaschintawar1173 remains same, water level stays the same even with ice
@@devonchristopher5837 ????
Lol you really would have to know almost zero about science, to think a nail changes anything about this. This is literally elementary school science.
Derived the equations of motion for the inverted pendulum on a vibrating pivot for my Classical Mechanics class. You can find it in Laudau's Course in Theoretical Physics Series, Volume 1, Mechanics.
Wife : Goodmorning Love what will do today ..?? Walking? coffee ?
ActionLab : Well ... I am goint to vibrate a huge jigsaw in the living room and you are going to push a pendulum with a stick...😁😁
Nice video.
I love how the music matches perfectly with it 4:33

Amazing video , loved the simple saw idea
I did all these in my childhood.....still didn't know there was science even behind this😂
is there anything without science behind it?
Lol compared to what else behind being things?

I can see a couple of kids playing with a reciprocating saw with a blade attached to another blade in the garage
video games would become obsolete
@@mayar9928 Homeopathy, psychics, dousing rods, "alternative" conclusions from various forms of science denial, etc. Granted, you could argue psychology is relevant to understanding their perpetuation, but, evidently, psychology isn't a science. Which is a good thing so we don't have to worry about the Dunning-Kruger Effect and falling into one of the above items.
Please drop a sheet of paper in a vacuum. Vertically and horizontally. It would be so satisfying to watch it fall straight down, without a flutter. But horizontally, would it bow in the middle???
@@Belowtheroots so gravity is pulling equally on it at the centre as at the corners?
@@UnbelievablyGauche ugh, yeah? Why wouldn’t it be?
@@jamesbizs isn’t there more weight in the centre? I knew that was a stupid question when I asked it. Edit: if you imagine 4 people holding a blanket at the corners, it would dip in the centre. That's my thinking.
Even better: make a small parachute with a weight at the end of the shroud lines and hold it “upside down” (weight at the top, parachute dangling below) and release that in a vacuum. It should fall with the parachute part remaining at the bottom and the weight up top.
@@UnbelievablyGauche Remember that acceleration is not dependent on weight (or, more correctly, mass). That's the whole point of the experiment of dropping something in a vacuum that is normally highly affected by air resistance (like a piece of paper or a feather).
Make a video on quantum computing
Dude. I love you. This is just great. Also opening eyes through experiments like this gives me (a boring 30 yr old thinking these things all the time and now understanding way too late why I wondered what made me like certain teachers and some not. The creative ones who always put in a twist that blew our minds were without a doubt the ones most kids enjoyed and why most of my school liked chemistry. The teacher made miniexplosions and showed us a lot of experiments so that stuck with us. And through these creative ways of showing science I personally believe is the way to enhance the curiosity to push science forwards and think outside the box to bring something we can use in the future. Something we can’t even imagine yet.
P.S. To anyone reading this I want to say: Stay curious! Find what you love and keep at it. If you have trouble finding what you love - try to remember what you love doing as a kid and/or still do that brought you the most joy. If you want to turn it into a business to make a living out of it = check out what businesses are built around the thing you love and do that. And if you want it just as a hobby - just do it! You’ll start to see more happy moments in 6 months. I promise. ❤️
This is one of the coolest videos you’ve released yet!
Up it goes, up up and away!!
could you do this with more segment to make a no gravity worm?
Interesting battle between gravity and inertia. I had a really great physics teacher in my senior h.s. class, and this guy reminds me of him. Mr. Rosenblum had a more laid-back personality, but he was very good with physical demonstrations that helped us students to understand some of the principles and forces in physics while also making it more fun.
Now we just jiggle a spacecraft, apply some assisted lift and we have a hybrid gravity propulsion vehicle HGPV.

Very nice. As always, short and sweet and to the point. Thumbs up. Thank you.
I think that Mrs. The Action Lab deserves a little more recognition in this video.
2:30 perfect for an out of context compilation LMAO
Woaw what a best video ever seen.
I haven't even thought about this.
Nice video
At 1:50 I can see the gears turning on what his hands are supposed to be doing, but he nailed it. My brain would just shut down and get the movements 100% wrong
My first thought was to shift the center of mass to the short end of the pendulum. That way, the long side goes up. The torque Idea is cool and fun, however it does require constant energy input. Alongside with other disadvantages like noise.
This is a good introduction to torque. The background music is at an appropriate volume. Overall the video quality is great.
Thank you very much for this video. Hope you keep posting more.
3:32 Husband: look honey, I discovered a free alternative to Viagra.
Wife: I wouldn't touch that with a ten foot pole.

This is the only channel that makes physics, a course I’ve chosen to replace with ap bio, interesting. I’m aware this is a superficial depiction of this topic that lacks in the equations/concepts associated with it; but, I guess this is what you have to do to hook our short attention spans.
Tbh when i saw this on steve moulds channel something didn't quite click but when i saw ur video its was really clear
He:Inverted pendulum
Me:Inverted bullet
Kids detected! CALL NSA!
Dude this is prob the coolest thing i've ever seen involving pendulums
You should link the other popular channels that covered this. I think it was Numberphile that had a guest interview explain the math behind it.
i would suggest modulating the speed of the sawzall power tool with regard to the periodicity of the pendulum for most efficient torque.
I think you have the inspiration for an amusement park ride with that double pendulum or even just the inverted one. Nicely done.
4:28 reminds me of the way a Tilt-a-Whirl works.
or get a long pole, two elastic bands, tie them a foot down the pole at opposite sides and then drill a hole between there these bands are through the pole, attach a 2 foot long stick or whatever and then attach the bands to the END of this stick on either side (following the pole, no bends or curves) and boom.
Pulling the stick to the right will cause the left band to stretch and pull the stick to the left but due to momentum the stick will continue moving which will cause the RIGHT Band to stretch and pull the stick to the right but due to Momentum the band to the left will stretch and so on until the stick stops moving, add some weight to the stick and stronger bands to adjust how long it swings for.
This version (as Copyrighted by me, Patent Pending (Jokes)) will allow you to do everything without ever moving the main pole.
I like the way you solved this.
Reciprocating saw was best wae.
2:14 I'll just do it at the neighbors. Bill won't mind
Easiest upward pendulum : Take a pendulum. Take its stand and put alot of weight on it. Drop it from the sky. The upper stick first wiggles and then stays straight.
The look on the lady’s face... 😂
Thank you both for the video 👍🏻
5:03 The face that accurately describe why to not do this at home.
Such a simple concept, that was very cool
This deserves more views
Wow, what an idea! Now I get to do the analysis of this experiment.
Can you suggest any application of this experiment?
4:30 ha ha center of gravity go brr
Your videos have helped me apply physics and math to building tools. Thanks.
Now I know why the pivot point was oscillating harmonically in the inverted pendulum lagrangian problem.
We are gonna make an Inverted pendulum.

Explaining very effectively 👍
Excellent and valuable information for students
Pump energy into a mechanical system, observe system change its behavior, conclude that something unrelated has changed.
This is exactly how lasers can cool down objects to near zero absolute: use one well defined motion (laser light) to eliminate random motion (heat).
00:51 if there is no friction it will rotate forever, not back and forth

Unbelievable experiments..mind blowing experiments Full support from #india...✌✌✌
Loved it! thanks man!
Bro, but you can do this simply by using a bar/pendulum in which mass is non-uniformly distributed {i.e. center of mass should be at the side of bar from pivot point} .....
Then also stable equilized position would be towards upright....
By the way very nice video bro. Love from India....
Science does work! And that needs to be shown along with concept in classrooms... Nice content!
Have to learn more from him very good things he is teaching intrested
4:08 when you tryna impress her in foreplay
Very brave of you, Mrs Action Lab.
Sir can you make experiments based on Quantum physics
Excellent
Very cool!!! Learn something new once again! Thank you so much!! Much GRATITUDE and Love!
This also works for continuously flexible assemblies, like bike brake cable outers, net curtain wire and some stuff ropes
Thanks, I've wanted someone to do this for a long time.
I once saw a bunch of straight rods connected by ball joints. Of course the thing collapses in on itself, but it stood upright once they vibrated it.
You only have 1 joint but it's still the same principle.
I actually asked you to do this ages ago but you can't read all the comments naturally.
I bet whenever we figure out anti gravity technology we’re going to look back to videos like this and say “dude we were so friggin close!”
you could also insert something really heavy, inside, below the pivot axis
you just invented a self-erecting sword-saw
The look of horror towards the end in your friend's face...XD
Who else is smirking when he does the "jiggle"
Energy v gravity? You continue to amaze me.
Very good example
Her reaction is so sweet haha. Funny and impressive experiment!
5:04 Me without Homework, when teacher asks to submit it
I have a doubt.
We can not create a fire in vacuum because of no oxygen.
But if we cud observe it without Oxygen how will it look in vacuum.
I want to know how will the refraction of the light of this flame in vacuum look like.
Sir can u make a video explaining this. Pls sir🙏🙏🙏🙏
This is cool. I never knew this reaction would happen
