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.

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!

@@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 way of demonstrating the things easier and faster. I swear couldn't understand it better from anyone else.

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.😊

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).

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 KZread 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 KZread video that explains how to tie knots that won't come undone.

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

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.

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.

Very nice concepts.

Man ! love this

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?

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

It should be pointed out that the more pulleys one uses to lift the longer stretch of the rope needs to be pulled for the same lifting distance.

Still only a matter of perception. 1. Three things changed in your system. 2. The spring scale is inverted so of course, the measurement is going to appear to be less because you are pulling from the opposite way. 3. The pully is removed from fulcrum, and added to the weight, and your personal weight is no longer putting force on the spring scale, but only suspending the combination of the pully and the weight. Therefore, the pully is not part of the fulcrum, but part of the weight, and the force is no longer under pressure, but in suspense. The hand in suspense tells the truth that the work is made more difficult in the configuration of the pully attached to the weight, and that is supposed to be the importance of your demonstration, not shifting the importance of the work the pully does over to how much the weight weighs. It is much easier to push than pull, but that does not mean that the pully doesn't make the job easier in the proper application. Is it easier to push or pull a cart? Pending weight distribution, I personally prefer to pull the cart rather than push the cart, but I'm certain your preference of mode is rather push than drag.

What is the dependant, independant, and controlled variable in this experiment
