Any one else here obsessed with physics?

[grommet]

I just realized it is a funny way to put it (not trying to make a joke) but I have been going round and round with ChatGPT trying to understand Conservation of Angular Momentum.

After a long tie I think I realized my problem understanding it is because I am autistic and think literally. Angular to my visual mind means angles, but the subject is about rotation more in a circle. I could never put away the image of an angle, like a triangle, so it made no sense to me. I'm wondering if many of my problems understanding things in physics is because of my synesthesia and total visual thinking. I experience everything as an image. It all translates through images so a literal image that is not what the word/s intended will make me lost.

I remember years ago walked park near by saw kids om merry go round had strong urge to talk to kids and explain angular momentum to them as I remembered being their age and not getting it. decided not too. Also was at airport years later and small child asked why the tips on wings on plane same thing bit my lip.

I hope you saw its all about conservation of energy at its root. Energy has to go somewhere turns into velocity. Or
torque force times distance the shorter the distance the less force needed and the less energy has to go somewhere
greater velocity. I would not fell bad I'm a visual thinker, can just see this stuff. Your way of visualizing is not that un common, even among NT's I could not see it until I took physics courses, Now I cannot unsee it. Reminds me of a joke I could not get for years, You can not have your cake and eat it to. To me it was literal I got the piece of cake why can I not eat it.

What do you mean about tips on wings on airplanes? I do not think you are talking about winglets but is that it? I cannot remember the advantage winglets provide. My instinct is to think about Bernoulli but I think it has more to do with smoothing airflow.

It is impossible to have a piece of cake and also to have eaten it. One hand clapping also bothers me, the reference people make to it and also a tree falling in the forest, does it make a sound if there is not a person there. Of course it does. Also, one hand cannot clap in the way it would have enough velocity or sudden deceleration against itself to produce a sharp slapping sound.

I did not understand your explanation. It is me, I am stuck on understanding conservation of angular momentum. For years nothing seems to be able to explain it to me. Conservation of energy I like, that makes sense to me. Torque confuses me. A twisting force exerted when a force is applied to an object not at its center, causing rotation. Maybe I do not have that right. It is what I think I remember.

Heat makes a lot of sense to me and also temperature. I worry a lot about the heat my PC gives off, not the temperature. It is well regulated and no components will be harmed because of high temperatures but I can be bothered but the heat. |

I am working on doing the experiment with the coffee mug with a cord tied to its handle and the cord laying over what I am going to use, a wooden dowel. If I can do it right after I release the coffee cup the long hanging cord will experience some things. The pull of the weight from the cup will extend the outer edge of the cord as it hangs over the dowel but the inside curve will experience compression because of the turn and the friction against the dowel. The difference in length will cause the free traveling cord to have a curve in it that will make it begin to wrap itself around the dowel.

Conservation of angular momentum should make the cord speed up quickly as it wraps around the dowel and its length becomes shorter. The increasing number of turns from the cord around the dowel will create more and more friction and so slowing the coffee cup down so it does not break when it falls.

The tip of where the air flow on both sides of the wing meet causing turbulence reducing lift the tips moves this turbulence away from wing tip restoring lift on the whole wing. Torque is force times distance a lever and F=ma
when you move a mass energy is required as more energy is added it causes the mass to move accelerate. going in a circular motion is acceleration. Temperature is movement. of atoms, again conservation of energy it takes energy to move any thing. The faster something moves the more energy. I'm not good with written descriptions can just see it in my head. We are not that far apart in how we view things only difference is I took physics courses.

I am so happy about your explanation of winglets. That is the clearest best explanation I have been told. Thank you. What a clever invention.

I am trying to understand the rest of what you taught me. F=ma is still confusing me because I once heard something I must have misunderstood, maybe you can tell me. It was about force. Something about F=ma2, the example being Willem's Gravesande talking about velocity of an object and its effect on impact. That a lead ball dropped from two feet onto clay would make an impression twice as deep as dropped from one foot. The squaring confuses me and I have never heard of F=ma2 anywhere else, that is why I think I have it wrong.

Temperature is the speed of the movement of atoms in a mass or maybe there is another way to describe it. I visualize atoms being active in fuzzy movements, higher temperature faster movement. Heat being the total mass of energy in an object. Tip of a needle heated to 500ºF, swimming pool heated to 75ºF. Enormous energy available in the pool, almost nothing in the tip of the needle.

Putting energy into an object confuses me badly. I see an object as solid and no way to put something into it. I know I am wrong because Einstein had proof objects had energy and when more was put into them they increased in weight but I am baffled about it.

Thank you again for the winglets, that was wonderful.

I remember high school physics the last thing the teacher said was two things F=ma and you cannot push on a string. The square is because the energy of the falling ball is spread over two dimensions on a plane X and Y.
This is all Newtonian physics, much simpler than Einstein's stuff.

I wasThInking about it last night your like me like analogies in the form of mental pictures, some pictures are complicated so others put it out it in the form of numbers manipulate the numbers and then it can no longer be pictured, E =mc squared looks nice but it took a lot of mathematical manipulation to get there the original picture that Albert saw I can see. F =ma Newton got by mathematical manipulation. Newton was not a visual thinker math was easier.
