Absolutely one of the most succinct and clear description of momentum, inertia, mass, direction and torque i have had the pleasure to observe on you tube. So much so, i am some way in retaining the information in one sitting. Will leave the math to others.😂 WELL DONE ✔️
@23:23 The moment of inertia is very different, but not because of easiness of ration (which is a consequence, and not a reason) but because in one case the (same) mass has to traverse very short (circular) distance, while in the other way ( towards the edges) it needs to traverse very long circular distance (2*pi*r) created by the rotating edges, in the same time. So in the second case the circular speed of the mass, will be vastly different, and as such the accumulated energy (momentum) will be a lot higher. A very good, and highly recommended reading, on this topic, is "On The moon rotation" by Nikola Tesla.

Great stuff! Now do you want to consider some other possible reasons for this physical universe and how it functions? Like what causes inertia in the first place.
The Legend! I have a question about conservation of angular momentum. When the coin is loosing speed and the angular momentum start decreasing, the coin start "this procession thing" (42:05), can at this point the initial angular momentum be restored with increasing the speed of the coin? Imagine that the coin has a motor that will accelerate when the coin is on the edge of falling, will coin acceleration restore the initial angular momentum? If this is true, than universe is powered by magic 🙂 Why? Imagine two coins with the motor, both are doing the "procession thing" in exactly the same way side by side. The difference between the two is that the coin A comes to this is state from upright position at higher angular velocity when losing angular momentum, when the con B is in this state from the beginning, with lower initial angular velocity and lower initial angular momentum then coin A. At this point, when the coins have exactly the same motion and angular momentum, the both motors start accelerating at the same rate. Will both coins from now on have the same angular momentum?
That was really good - many thanks. May I ask if you would consider a brief video explaining motorcycle 'counter steering' (ie steering right to turn left and steering left to turn right) which I suspect is also a result of conservation of momentum. Thanks.
Fun thought…. Does the spinning wheels on a bicycle give you the stability you feel when the bike is in motion? Yes? Now would that bicycle still be stable if its wheels were rotating but the bike is not in motion? ( wheels are on a treadmill)
@vara1499 a bicycle’s motion is linear, only its wheels have angular motion. (And they have a very small moment of inertia compared tho the linear inertia) The question is: if you remove the linear motion (momentum) but still have the angular momentum; is it just as stable? And if not, what is happening in nature, so that linear momentum causes the person with his apparent centre of gravity that is more than three feet above ground to be stable?
@4pharaoh if you put a long axel through a bike wheel, hold the wheel vertically and have someone spun the wheel you will notice it's strong aversion to tipping off the vertical.
@@someguy-g4r of course you will, (Not as relevant as you imply). Now imagine that bicycle spinning on rollers or very slippery ice with no forward linear motion for the bike… if the stability was because of the angular momentum wouldn’t you imagine the stability would be the same, as a matter of fact: since the tires spin more freely on ice the cyclist should feel even more stable, but we viscerally/ intuitively know that is not the case. So what is nature doing to make the bike stable if it is not because of the wheels rotating
This was very interesting. I'm just starting to study physics as a layman....Q: I work in a produce dept. When I pick up a 50 lb bag of potatoes by the end and lift it feels very heavy but I discovered long ago that if I pick the bag up in the middle, one hand on each side, the weight flops to both ends of the bag and im able to lift and transport much easier... Is this similar to the 2 pipes?
I would just guess and say, its partly related to weight distribution as well as muscle distribution. When the entire weight is straight down a smaller number of muscle fibers support it during the lift. When the bag is doubled on the center, more muscle fibers at other angles in the arms support it. So if feels easier because you are spreading the forces out over more muscle fibers. I have no way to prove this, but in my mind it seems to make sense. Because there are more strands doing the work in parallel it feels easier. When it's just straight down only a few specific muscle fibers do all the work. I think this makes sense. We don't realize that there are individual fibers that make up the muscles, and the angles of them and the weight distribution of the object effects which ones have to do the work to move something. Also the grip area of the hands increases so its not just a few fingers supporting the weight, its the entire hand /wrist doing the work. Just my thoughts. If I am wrong I would love a better explanation to learn from! But I think this explanation is on the right track.
Is angular momentum equivalient with linear momentum? Say an ice skater has a tennis racket in her hand and hits a stationary tennis ball that causes her to stop spinning, will the ball get the same momentum?
But if gravity acts on the object, by virtue of having been acted on by an extra outside force, naturally the object will have a different momentum. The object may try to return its momentum to the original level, but what does it have to do with the law of conservation of momentum? Doesn't this law only apply when there is no additional force?
In detail, yes, but momentum itself "overpowers it" on macroscopic level. So over "shorter" period of time you can neglect gravity and focus only on momentum of observed object. Point of this lesson is to get a hang of a principle that governs bodies that spin. It's easier to understand it if you don't try to account in for gravitational force of Moon, Andromeda, friction etc. That law applies when there is additional force - 34:30 - when solving problems like this you can use graphical (vector) method or numerical (math) method. You just balance forces out. Jason is better at explaining you should go for his lessons :)
Object in orbit loose velocity and will eventually reenter the atmosphere atmosphere if not given a small push. The gyros cant add velocity they can only maintain position.
Another fun thought… You’re floating in space between two floating Teslas It takes substantial energy to overcome their inertia and push them apart. So… where is this resistance coming from? Yes inertia… but what is nature doing elementally and universally to produce that resistance to change. (AKA: What is the Origin of Inertia?)
The answer to the question "what is the origin of inertia" doesn't exist and it's good not to look for it in physicists either, because it's a waste of time, physicists don't know anything, they can't even explain what matter is. It is even good not to study physics theories that exceed a certain level, namely those of modern physics.
I think no one has an answer to this question. Physics tries to give some explanations, but they are partial and presuppose answer to other "whys". The way of searching that physics proposes must be abandoned, because it leads nowhere. Moreover, the search itself must be abandoned. The fact that nature does not allow itself to be explained is a signal that the wise man must understand and act according to the signal he received. He understand that the purpose of man's life is other than the continuous decifering of the mechanism of nature and that this is a path he is not allowed to follow. He has to find his way.
@@marianl8718 If Newton or one of the other kings of science thought like that we would still be riding horses instead of Teslas. Be a King. (Prov 25:2)
Newton himself said that although he could find a formula to give the intensity of the gravitational field of a body at any distance from the body, he was not at all interested in finding the explanation of the intrinsic mechanism of gravity. The old times, when scientist barely found anything to light their rooms with, but with their minds enlightening the whole Universe, were superior our times, when technology brings only modern slavery and the degradation of life.
I had no idea that's why they tend to put a spin on space probes. Makes total sense though! You truly have a gift for teaching. I would have loved having you for a teacher in school. I'm assuming you are a teacher/ professor. If so, you definitely chose the ideal profession for your skills. The world needs more teachers like you! 🫡
I'll watch this, but why does my magnet smell funny after a few minutes of spinning it from the cool motor thing? Yes, I'm still playing with it.... Lol What is it from, and why does it have that distinctive smell? Almost like rusty b.o.? Lol Thanks Buddy 😎
