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
Thank you for making my understanding of levers a "whole lot easier"!
Thx for helping me but I still do not like science

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🙏
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?
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...💖💖💖💖💖💖💖💖💖💖💖💖💖💖💖💖💖💖

Thank you for this my teacher has sent this to me and this helped me alot😊☺️❤️
Mr. Hanifan ?
Glad it helped!
wow this is pretty good
Thanks man!
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 for sending a wonderful viedio for homework
I cannot wait to show this to my students on Monday
Hey! We would love to hear back from you about how the students like the video :) We hope the video was helpful and for more fun and simple science learning, check out the other videos on the channel 😄
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
thanks for showing us how it works
Great vid m8
Thanks I love science now thanks for your great 👍🏻 videos
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!!
Nice explanation 👍
i just saw the vid and i like it
Another excellent video. Thank you!
this is so cool!
I subscribed this channel FUN SCIENCE DEMOS
Thanks we love to hear that! Make sure to tell your friends and family about us !
Explained very well👍👍👍👍
yes

Can you explain more about why it balances and does not prevail?
Thank you so much for creating so much for creating this channel and for putting so much effort into it! My son is now having a lot more fun and understanding of science :D
so much so muchso much
Well based on what you said,
You made my test EASIER
wow
Thank you 🙏
Thanks I subscribed already ur video was so helpful 😊
Thanks for subscribing! We are glad you liked it :)
I love the scientists call... part. It makes you feel like he is just a normal guy not some nerd
it's amazing but please could you possiply put the steps for how to make the last modle
Who else is just here because of homework
me
me to
ME!!!

to cool
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.
Great!
It's cool
You make my work more easy
so glad to help
thank you for the vid it helped me so much thx i have a science test tomorrow plz give me good luck

How did the test go
i subscribed this channel
SapphireonPlayz //FlorenceRivera no proplem
Problem
Thank you.
its cool
fun
Nice 👍
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.
i subcsribed this channel
SapphireonPlayz //FlorenceRivera the first like you ever got
Iam mahmoud eid lam egyption your studies it's my favourite hope I love you M*R
would've been cool to have spring scales on both sides

Thanks I didn't understand at first thanks
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
2020, anyone?
Rlly 🤦♂️
me
I'll pass lol
Its 2021
2022🎉
cool
nice
But you don't explain why
nice wheel BARREL
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.
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.
Anyone here for homework lmao
the first one was a class 1 lever and the second was a class 2
that was great... but why does this work like this?
this video is also very simple
make work *easier*
Please say hi to me Jared :(
so much elly bowden
1000 grams equals 1 kilogram.
Science...
😮
i was just thinking that a magnet near the pivot point might make the object lighter
🧲🤔🤷♂️
simple machine
hola soy el cejas coooooooooooooooooooooooooooooooooooooooooomoooo buen video
va bro,k te metoun castañazo o un placa
quiero un pedido especial

Anyone else here because of school 🏫?
😊😆😅😁😄🙂😂
👇🏻
who is here bc the teacher said. to? ( online class)
me
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.
POV your watching this for science
It’s harddd😭
My teacher let me watch this
Another one
Who’s here from science class 😑
LMAO its Carter
@@rocketninja942 HAHA
yodie gang
Mis bosstrom’s class home work
hi
lol
I am
nice beard (:
But he's not even lifting the weight that much!
