Thank you very much! i need this for my performance task :D
plz tell that what other energy is converted other than kinetic
Gravitational potential energy to Kinetic energy
It is leaning toward one side although the mass on both the sides are same..what to do please tell me reply fast as i need to submit this project tomorrow itself...please..otherwise really an amazing idea..
So how'd the project go
are there any use of this in daily life? can you please give examples?
Cranes, pulleys, weigh-lifts etc often use this technique, where something is first mechanically lifted to a high height, and then allowed to descend gravitationally over a period of time, thereby using that gravitational potential to use the energy later. It's become a very popular way to store energy. E.g. when a region has high wind, for example, and a windmill, but not all that energy is used at the time. The excess energy can be used to lift a load (could even be water!) to a higher level/reservoir. Then, say months later, when wind levels are low, one can allow the weight/water to descend and power a turbine while all that mass descends again... Have a look at pumped storage hydroelectricity!

Amazing

What kind of foam was used? @ Think Tac
Any kind of rubber or foam pieces. We have used a thicker foam, about 1 cm in thickness as well as a thinner foam, about 2 mm in thickness
Good
But, I want some matter about this experiment
Is the kinetic energy from the bottles spinning ? cuz my bottles cant spin
The bottles fall down due to gravity. And anything that moves is said to have kinetic energy. Is that what you are asking? If your bottles aren't spinning, then reduce the weights, or the turns on the string, or the type of string. You have to minimise the friction between string and stick to ensure spinning, but you still need some friction to ensure there's no slipping!
How can we explain it sir?
Please tell us sir
Any object wants to fall down. Here, we reduce/control the rate of falling by adding a weight and attaching it to a string wound around a stick. This causes friction and slows down the descent
Hi
What’s the point of the bottles
Even if the bottles weren’t there would it show the same conversion
@thinktac
Purely for aesthetic value, to see something rolling down nicely, and which can be inserted into the skewer. You can try with any other appropriate material; explore and vary: that's the main idea of ThinkTac TACtivities.

What can be the conclusion??
What can be the conclusion? @thinktac
Conversion of energy from potential to kinetic. And also frictional force between the string and the skewer preventing any slippage... More turns and it will stop rotating altogether!
Can i ask on how this works?
That's for you to make and tell us! Anything that is at a height and let loose will fall, right? What is it in this case that is helping it to fall? What is kind of slowing down its fall? Does the weight matter, i.e. the tension in the string? What about the type of string, or how many times it is wound around the skewer? What is the force between the thread and the skewer?
What type of energy is converted here explain
pls explain
Yes can someone explain
The energy is converted from gravitational potential energy to kinetic energy. The fly wheel is pulled down by the earth (gravity) which causes it to move down and make the bottles move as well. Remember energy of movement is kinetic energy
@@Legend-kr5kv thank u

straw needed?
Straws are used as ducts in the cardboard holes so that the threads can be nicely placed in them without too much friction being caused. Small pieces of stiffer straw are ideal
i did this but the thing won't fall down u have to pull it down
That's where you'll have to adjust the thread and loops such that it comes down by itself. Using different thread, or looping it a fewer number of times, helps in reducing friction so that it comes down more easily. Also try reducing the hanging weight, and make sure your flywheel is nice and symmetrical and not biased to one side

@@veenachawla6154 You have to push the water bottles close to the cardboard cylinder and then it will fall down
@@Legend-kr5kv I tried this but it is not working.. the cardboad roll get biased on one side and then the flywheel stops working...what to do now? Is there any other way to correct this?
Era meglio uno yo-yo...
