Yo! I wish I had seen this video during my 12th standard.. All those pulley problems made me pull my hair so bad.... But this experiment makes it so clear. Well done man! Awesome! I am glad I watched your video. May you make more videos! Thank you!
Thanks for saying this. This is the topic that got me diffident in physics. Clearly, it was due to lack if illustrations like this. I was lost in thoughts wondering how the drawing on the board practically works and I lost the whole idea on how it makes things easier. God bless Sir for sharing.
My 5 grader loves it! Thanks
Weel and axle
Love
Well I saw this in my 10th std..I'm lucky 😅
This is by far the best pulley explanation video.
He didnt even explain anything
there is a mistake
@@Son96601 seriously
This is the best pulley explanation I have watched. Thank you for making home school easier for me.

@@funsciencedemos sir here u should use the word mechanicle advantage it will surely ." Sone pe suhaaga"🎂= 😀love from india
This is a fantastic demonstration that I am sharing with my students, since we can't do it in class due to distance learning. As a physics teacher I do want to nitpick that this isn't making the "work" easier, because work has a specifc meaning in Physics of Force times Distance. *W= Fd* In plain old English, yes, we can say it's making the work easier, but no machine or device can reduce the amount of work it takes to do something, as that would break the first law of thermodynamics. Breaking the laws of Physics is strictly forbidden in my house (and universe). Thanks for the great demo!
so why does it take less force to pull the weight attached in the pully can you please explain it to me??
@@shouryaupadhyaya2036 it's because in the 2nd one, the tension is getting applied from both left and right side whereas in the first one tension was only coming from 1 place which was applied by us
@@shouryaupadhyaya2036 because work = force x distance, if you exert a smaller force over a longer distance, it will be equal to the work done when you exert a large force over shorter distance. With hydraulic systems or pulleys, the output distance is longer than the input distance.
I love the teachings
Thank you so much. I am 8 years old and I am able to understand this . thank you once again
Wow I'm doing my work at home because of the Corona virus and my teacher sent me this video and it has helped me so much wow
Same
Charlie's Gaming and CHALLENGES!!! Same
Excellent demonstrations
These kind of videos make learning science far more interesting than the science 📚 books do. Thank you funsciencedemos....
Glad you enjoyed it!

This is by far the best pulley explanation video.
One of the best examples of the amazing world of pulleys..
My teacher always requests to watch you!!
Very well explained. Thank you so much.

Great video.
The only thing I would love for you to add is the relationship between the number of ropes that are suspending the mass, and the reduction in force needed to lift it. In the first example (fixed pulley) the mass is suspended by only 1 rope, so their is no mechanical advantage. In the second example (single moveable pulley) the mass is then suspended by 2 ropes, which halves the amount of for needed. The final example (two fixed, one moveable pulley), there are 3 ropes supporting the mass - meaning one third of the amount of force needed.
It would also be handy to add that the trade off for reduced for is a great amount of rope needing to be pulled out to see the same change in height. The amount of rope needed to be pulled is simply a direct multiple of the number of supporting ropes mentioned above. (ie. 3 supporting ropes = 3 times the amount of rope needed to be pulled out).
Also there could be a distinction between a _force_ and a _mass._
Jarrod: Your explanation is WAY better than what's in the video.
Nice explaination
This comment has made me understand more than anything else I have seen
@@sonofjimmyray I'm glad it helped. :) I wish I'd proofed it before posting it though! It's not written well. :)
Great video, and thank you so much for including the flag at the end!
I'm in 10th grade and this helps me so much... Thank you!
I recently purchased a pulley system to hang a bug repellent canister from the eaves of my house. The pulleys are great little gizmos, but having never rigged a pulley system before, I needed instructions, and there were none. I scoured the Internet and TH-cam to find a simple video that explains how to rig two pulleys, and I finally found funsciencedemos, and low and behold, I now know how to rig a pulley system. Thanks Jared. Now, I need to find a good TH-cam video that explains how to tie knots that won't come undone.
😑
great explanation
Great video, very clear to follow.
We love to hear that! Don't forget to subscribe and tell your friends and co workers about us!
Ok thank you so much for the follow I love you
sorry i can`t so sorry but your amazing
It's so easy!!!!......
The explanation made my life easier like the pulley......this is an awesome video.....
Wow! Such an amazing demonstration. My book just came to life ❤️.
Glad you enjoyed it!
@@funsciencedemos :)
I like all your videos
i'm watching this in school unlike the other videos they show us i actually like this guys videos
we are so glad! science is so cool!
Definitely going to help me with my science test. Thanks so much!!
same!
oh my god you are seriously the best one. have no words the explanation the examples were just out of the world. wow just wow. no words can describe it. gosh loved it just wow
Thank u sir for explaining every topic in fun way , with experiments in every topic .
You explain very very well ....
Thank u very much for that
Thank You So Much this helped me with my study!!!!

It is the best video for understanding
Great work number one.
I get it, nice.
Thank you so much for this!!!
Great video!
So clear! Thanks,mate!
Thank you so much for this video, I thought hanging a canoe from my garage rafters would be simple...nope. This helped tremendously, I was so happy when I gave that first pull and it finally worked. Again thank you so much for making this.😊
Very nice concepts.
Thank you so much for this! I will show this to my students to help them in class.
Glad it was helpful!
In case of a simple pully, you can use your own weight as force, hence, it makes work easier.
In case of a moveable pulley, it really does half the required force because the other half is handled by fixed string
This completes the above video, its a very important note while explaining pulleys...…
WOW! It is a very nice example to understand simple machine.When my mam explained I had small doubt but after watching this it is clear.THANK YOU and LOVE YOUR EXPERIMENTS
So very glad to hear it. Thank you. For more fun science demos, please subscribe to our channel.
nice and helpful video
Nice and simple video 👍 It helps me understand alot
wow this is really informational. im gonna add some of this information on my work
very good
this video taught me a lot : )
very nice presentation im on online class now in my engineering dynamics i reviewing i am confuse on some pulley problem especially when the string is fix at bottom now i understand thank you very much
Very informative its makes pulleys more understandable for me! Thanks for the video!
we are so glad to help!
useful video
very informative. Thank you
Glad it was helpful!
Very nice and good
SmarterEveryDay brought me here for more *snatch blocks*

very nice experiment !!!!!!! understood at once
thanks so much my head couldn't get around it keep doing what y'all r doing
Great vid love the enthusiasm
Great Video thanks
Great work dude
I was struggling with this in physics but this made it easy
Thanks
Glad to hear that! Check out our channel for more physics demonstrations :)
Good now i understand in this topic of pulley
Really thanks for the video.
My first language isn't English and my physics is not very good, your video really made my English and Physic subject skill better.
Once again , thanks so much
Hello, and thanks for your comment! You can easily translate the subtitles into your native language by first turning on the English ones and clicking auto-translate, then selecting it from the drop down list. Science is so cool!
Your video is so informational!
Ancient, simple and so effectively
this helped me alote
too bad it did not help with your spelling :)
Just to specify. The work you have to do to lift the weight a given distance is not LESS using a pulley system than just a straight rope. However, depending on how you have defined EASIER it might be just that. But to lift the weight 10cm above the ground takes exactly the same amount of work (assuming friction free pulleys) whatever number of pulleys that you are using. If the pulleys are not friction free it takes even more work to lift it those 10cm using pulleys.
jared you are hte best!
Great job! You should probably mention how you have to pull further distance because of the conservation of energy law
sh
This really helped, me thank you so much
CONGRATS ON 100K SUBS!!!
Great, very well demonstrated..thinking of buying a block and tackle for my stairwell to help taking stuff up & down stairs....
Thanks for help with my engine hoist
Wow! I feel smarter for having watched your video. Thanks for that :)
Thank you 🙏 sir your explanation is excellent
Great helps a lot
Thank you sir
A good point to make is that it is not about the number of pulleys it is about the connection points that are fixed and count as another helping hand in the force lifting the object
block & tackle pulley! no kidding i'm a science newbie but you helped a veteran amateur digger out big time
Thanks for the tips. :)

Love science and pulleys
Science IS cool and so interesting when explained the way you do it. Thank You. P.S. The block&tackle you showed would make our work 6x easier, correct?
Glad you enjoyed it!
AWESOME! Understandable
This is NOT boring

This is awesome. I just wish you could explain the difference between the first example and the second example better. Why does one pulley at the top make such a big difference then the pulley attached to the weight?
Archimedes used a system with three pulleys that accomplishes the same reduction in force as a block and tackle with six pulleys. As your example of where you connected the first pulley showed a difference in force, the arrangement of three times that same principle helps more. Three pulleys in a row, connected to the cross bar, from the cross bar through the first pulley then connected to the bottom of the next pulley. Repeat three times then through through a fourth hanging from the cross bar the the source of pull. Either a person or a winch.
thank you
Nearly got that silver play button.

THE block and tackle system 😁
nice experiment easy to learn. .....

Thanks it's useful
Thank you soooooooooo much
Where did you get those pulleys?
Thanks. This really helps.
Man ! love this
This guy is pullyng our leg.
Would be better if the spring scale measured newtons as well - and would say mass instead of weight because in physics weight is mass times g
great demo!!!
I know right
Thank you so much sir!
I couldn't figure out how fixed pulleys worked and this helped a lot 👍
