your explanation is so great. non arrogant and so stright forwerd. I am a designer, not engineer and i could understand every single word you said, and therefor i subscribed your channel . your studants are very lucky!!!
Nice English grammar my mate.
thank you so much!
@Ali Alqaisi more than great
MINOR SPELLING MISTAKE
Who else is just here because of homework

2020, anyone?
Rlly 🤦♂️
me
I'll pass lol
Its 2021
2022🎉
With the help of you my little sis is intrested in science
Anyone here for homework lmao
Thank you for making my understanding of levers a "whole lot easier"!
Thx for helping me but I still do not like science

I have an idea for a lifting force machine.
Step 1: Get hollowed out cube.
Step 2: Securely attach magnet to inner bottom of hollowed out cube.
Step 3: Place a lever on inside bottom of cube behind the magnet that's securely attached to inside bottom of cube so that one side of the lever is pointing towards you and hanging over the magnet.
Step 4: Attach a vertical bar to the top side of the part of the lever that is not hanging over magnet witch is securely attached to inner bottom of cube. Make sure the bar goes all the way up to the inner top of the cube barley touching it.
Step 5: Securely attach a magnet to the side of the lever that is hanging over the magnet that is attached to the inner bottom of cube.
Note: Magnets need to be facing each other with attracting poles N,S or S,N
Note: The lever is going to have to be really close to the magnet on inner bottom of cube because of how close those magnetic fields need to be to interact. But not so close that magnets can touch.
The magnet on top connected to lever is pulling the magnet on inner bottom of cube towards it and since the magnet on inner bottom of cube is connected to cube, this pulling force acts as a lifting force. Now at the same time the magnet on inner bottom of cube is pulling the magnet on top downwards BUT the magnet on top is connected to the lever so any downwards pulling force is being converted mechanically by the lever into upwards lifting force. Now if you know anything about magnets you now that there are magnets powerfull enough to lift far more weight then just there own. So essentialy this divice is exploiting the powerfull pulling force of magnets by mechanicaly transforming its magnetic pulling force into mechanical lifting force through the clever utilization of a lever, and walla stuff can be made to fly. Imagine if the magnets in this experiment where electro magnets so the ammount of electrical current going into them determined the ammount of lifting force that it would have. Now imagine this system being used as an attachment that could be placed under or ontop of vehicles to counter the weight of the vehicle and any cargo its carying. Now imagine if this was done with powerfull permanent magnets and turned sideways and placed in an electric generator and had enough strength to pass through the magnetic fields as it propelled itself forwards with its own magnetic pulling force. Signed AMA. If some one can make a You Tube video of this effect in action that would be great thanks.
What will happen?
look at dat spring stretch
now respect it
I watched 100 videos and then I found this video the explanation was awesome 🙌 I understood everything it’s my exam tomorrow and it’s gonna go awesome wish me luck
We hope your exam went well! We are glad to hear that you found our lessons helpful :)
But you don't explain why
exactly
Anyone else here because of school 🏫?
😊😆😅😁😄🙂😂
👇🏻
Who’s here from science class 😑
LMAO its Carter
@@rocketninja942 HAHA
Iam mahmoud eid lam egyption your studies it's my favourite hope I love you M*R
who is here bc the teacher said. to? ( online class)
me
Simple machines do not make work easier, but they can reduce the force needed to lift something. Work = force x distance
Which, in practical terms, is making work easier. *facepalm
@@mastermaniac1911 No, that is not true.
You are correct sir. He made a mistake by not pointing this out and using the proper nomenclature.
Thxs for making this video you are really a life saver and now I can make my marshmallow launcher by lever thx you for making this video Keep up the good videos and I will be happy :D
If your comments are here then be honest :3
lol
So...please help me out here! I'm trying to recreate this as a demonstration for my elementary class, but the science isn't working!! I'm using an 8oz (226g) weight instead of the thousand gram weight, and I've had to be creative as to attaching it to my meter stick (I've used an o-ring/caribiner and string, but all other materials are identical to Jared's. Here's the issue - when I use the lever, my spring scale measures MORE work, not less/easier :/ WHAT AM I DOING WRONG? I won't be able to sleep tonight until I understand this :P
Stevie......a quick suggestion....1) Are you sure it is an 8 ounce (226 g ) weight?....2) directly weigh the weight with the spring scale and see if it measures 226 g.....3) Spring scales can be very inaccurate unless they are calibrated with a known weight. Let us know the result...we can continue to brainstorm together.
Make your students do all the work. They can go to Walmart and get the supplies as an assignment.
that was great... but why does this work like this?
wow
Great teacher🙂👍

Nice video! I'm making a video on Levers in the human body now, wanted to see what else was out there. I thought you'd go over the 3 classes of levers, but that was a cool demo on the 2nd class lever.
Ture
wow this is pretty good
to cool
1000 grams equals 1 kilogram.
Science...
your explanation gets a thumbs up !!!!!!!! just superb , you explain us so easily by some experiments.........Thank you ! I have already subscribed your channel ....... You're a nice teacher .. I wish you get millions of subscriptions .......
Glad it helped! Mon!!
Simple and clear! Love it.
Thanks Tracy, for more videos just like this one be sure to check us out at ua-cam.com/users/funsciencedemos and do not forget to subscribe !
Thank you sir for explaining these things in such a cool way.
yaa
POV your watching this for science
I love the scientists call... part. It makes you feel like he is just a normal guy not some nerd
I don't understand how this works in terms of the formula used in physics. The formula is Force1 * Distance1 = Force2 * Distance2. Where distance is the distance from the fulcrum.
Cant lift this stuff if the materials to lift it arent up to it, eventually we will find something that we wont be able to lift with out technologies, because of the materials we know.
thanks for sending a wonderful viedio for homework
Waaaw....for the 1st time as a school student I think techniques of Simple Machines are AMAZING...thank u so much for this video...Looks like it made my day...💖💖💖💖💖💖💖💖💖💖💖💖💖💖💖💖💖💖
You're very welcome!
Can you explain more about why it balances and does not prevail?
the first one was a class 1 lever and the second was a class 2
Great vid m8
i subcsribed this channel
SapphireonPlayz //FlorenceRivera the first like you ever got
clikbate
Thank you! You made our homeschooling easier😊
Amazing explantion worked for me
No f l o r w e r e z z a, Its 2021!
i was just thinking that a magnet near the pivot point might make the object lighter
🧲🤔🤷♂️
thank you for making my work a lot easier with these demos. This is the youtube lab for online classes. Thank you so much!
Thanks I subscribed already ur video was so helpful 😊
Thanks for subscribing! We are glad you liked it :)
Thanks I love science now thanks for your great 👍🏻 videos
it's amazing but please could you possiply put the steps for how to make the last modle
nice beard (:
fun
i just saw the vid and i like it

Thank you so much for this series on simple machines. Super informative and clear with no filler.
I always struggled in my school days because believe it or not...I have always this weird ability to check the vibe test...but no teacher has this easy going, non arrogant way of teaching like you do...When I share this feeling to my fellowmates, they laughed at me because it sounds very ideal...but turns out it is not...I'm so happy to encounter this channel...never stop teaching and inspiring🙏
It’s harddd😭
Thank you for this my teacher has sent this to me and this helped me alot😊☺️❤️
Mr. Hanifan ?
Glad it helped!
Thank you you just help me cheat on my homework 📚 again post another video for social studies exam tomorrow
U shouldn't cheat cuz what happens in the dark ALWAYS comes to light so don't cheat and if you cheat you will never succeed. 💡✨♥️🤗
Thanks I didn't understand at first thanks
so much elly bowden
My teacher let me watch this
Another one
would've been cool to have spring scales on both sides

Problem
Do u have a girlfriend
why do you ask XD
Seriously he is taking about boring stuff but helpful for cheating in my homework and you little bitch is crushing on him he ain’t cute he ugly man but again helpful to me at least. I fucking hate homework bro so boring anyway bye

Thanks man!
this is so cool!
Bruh
I am
make work *easier*
ok so this video shows that a lever works but does not explain how/why a lever works.
Now 2024🎉
But he's not even lifting the weight that much!
Bye
nice
simple machine
It's cool
Another excellent video. Thank you!
its cool
cool
hi
hi
Cosine Error! Good video though. Useful when your digital scale can’t measure low enough. Set it to 1/10 the distance and move the decimal point.
nice wheel BARREL
You make my work more easy
so glad to help
My son's eyes lit up, he loves this stuff. He's 5. Good video! :)
