If we're going to make that correction, we should also point out that gravity is not a force either. It's an effect caused by acceleration, which can be produced by mass warping time-space, or by an or an object changing its speed.

It's far more likely that the Moon firned from an impact between Priti Eartg and Theia, which was a Mars sized planet. When Apollo missions gathered enough rocks on the Moon's surface, these proved that the Moon was made of Earth's crust, which was tossed into orbit during the collision with Theia And Theia's core went down into Earth's core.

[@tomcantrell5553]

Very well explained. I liked the simulation of the 1/R^2.1 vs 1/R^1.9 and the graphical representation of the differences in the shape of the gravitational vs magnetic fields. Nevertheless, I think it would be cool to see is you could shape the magnetic field a little closer to that of a gravity field shape. Perhaps a ring of magnets with all south polls pointing inward. then magnetic ball rolled past it would "see the same field in all directions around the rings. Next, you could try to orbit a steel ball around that magnet instead of another magnet.

[@as-qh1qq]

Just a correction, a balance of force isn't needed for uniform circular motion ( the acceleration would be 0 then ), just an initial velocity. Do preamble that u were talking in the objects frame.

[@mario_dc]

Exactly, it's the conservation of angular momentum what keeps things orbiting around a central body. Centripetal acceleration, caused by gravity, is what constantly bends the trajectory into an elliptical orbit.

[@as-qh1qq]

@@mario_dc I guess u meant angular, linear isn't conserved - force acting

[@amaneyuuki6569]

That's right. Centrifugal force is not a real force, it's only a force we define for convenience when we want to set the frame of reference that follows the rotating/revolving object. Even in that case, drawing the centrifugal force together with the ball moving in the same picture (0:55) is incorrect.

@@ABaumstumpf Lol, Newton is the one that explained it this way in Philosophiæ Naturalis Principia Mathematica.

[@AntonioAstorino]

I think a longer, thin wire would have worked better because it would have reduced the projection of the tension along the orbit radius, which positively contributes to the attraction to the central magnet and causes the smaller magnet to spiral in. In any case, it was a nice experiment :)

You also introduced quite a few more forces with that magnetic orbiting setup. There is the spring force of the rod pulling the magnet back to center, plus the tension forces from gravity pulling on the mass. I honestly think you'd have had better luck passing the cylindrical magnet through a plane of plastic and rolling the original ball magnet around that. You'd still have the polarity of the ball magnet mess up the orbit, but I would think that would be less of a factor than the additional forces from the rod.

[@truestopguardatruestop164]

The same thing I though: constrain the magnets with 2 frictionless planes

[@bigthahn]

Yes I was thinking this once the magnet began slight orbit he didn't continue to wiggle his hand which was the initial causation of the magnets beginning motion. If you continually applied the same spinning motion even once the magnet began to grab then I think, should it not continue it's orbit as long as you applied that same outward force with the rod?

[@fn3200]

In reality, to make two objects orbit each other you only need a centripetal force (centrifugal force is only the centripetal force observed from the point of view of the object that is orbiting). The reason why we only need one force (the centripetal one) is that in itself the object that is orbiting at any moment would like to travel in a uniform rectilinear motion (due to the principle of inertia), it is exactly the centripetal force that does not allow it, forcing it to follow a circular trajectory

[@rainbowevil]

Exactly, and if those 2 forces were balanced as he said in the video, it would travel in the linear path as you describe, which is clearly not an orbit!

[@fn3200]

@@rainbowevil yep, in reality centrifugal/centripetal force are just the same force observed (experienced in this case is better) by two different observers. Centrifugal is an apparent force. However I think he knows all of this but he used this (incorrect) example to describe in an easy and intuitive way the circular motion

[@blueckaym]

Very interesting! And I would really appreciate if you elaborate (perhaps in another video) on how Gravity results in stable orbits. It intuitively seems that the orbit of a body around another body (like a planet around its star) is unstable equilibrium state (it's not just a point obviously as it requires correct position and momentum). But I mean that even the slight offset of the perfect balance (and we know that very few things are perfect in reality) would potentially (even if in a very long time) set the body either no a collision course, or would eject it away of the other body (losing energy usually results in the first scenario). So it seems there is a phenomenon or mechanism that ensures a balanced state (at least for some part of the matter), but intuitive thinking of separate bodies doesn't work as this balance of the whole system in my opinion is result of all the bodies (no matter how big or small or many) works by simultaneous interactions between all of them. I know Lagrangian mechanics is good for describing such complex systems, but I'm not familiar with it or its maths. And also while I definitely support the role of Math in all the branches of sciences, I think it doesn't help with actually understanding or communicating how a given phenomenon works (except between mathematicians)

[@silience4095]

Because his explanation is wrong... The centrifugal force is not real, it's not a thing in orbits. Let's ignore relativity for a second and assume that gravity is a force. The force points radially inward, which moves the velocity vector around its parent body. It's just the inertia of the object that keeps it from falling straight down. It's like swinging an object using a rope, the only force is the centripetal force from the rope... the centrifugal force doesn't exist... it's a fictional force.

[@dustinc6869]

@@silience4095 Thank you. I also said something similar above. There is no centrifugal force here. An orbit is a body that is being pulled by a force but is free falling at an arc greater than the force. With no friction (no atmosphere), the object wont slow down and will maintain the same trajectory in a free fall around the object. Pretty shocked that this channel got it so wrong. Im usually really impressed with the other content.

[@totheknee]

All known elliptical orbits decay due to influences from the rest of the system. It's just a matter of time. But there are just so many orbits that last a "long time" in human terms, that short-term stability (on the order of millions of years) is highly likely. The orbits themselves are neither stable nor unstable in the sense you are talking about, there are just an infinite amount of them. If you perturb an object in a particular orbit, the satellite will just assume another orbit according to the observed mechanics governed by mass, velocity, and gravity.

[@blueobject]

Love your videos. Was always taught that centrifugal often gets confused with centripetal acceleration. Centrifugal force for orbits is a fictitious force. The force is centripetal towards the center. There's no outward force but the vector is in the direction of velocity of the orbit. The moon is always falling. There's no force. The proof is to remove the earth and the moon travels around the next major mass or theoretically flies straight. Great video! Love your vids.

[@FDroid01]

Pretty much what I think this is. :P The only real balance is entropy, or at least dissonant transduction i/e modulation of energy. I think without it... matter and all forces on it would resonate without interference, become a giant polarized mess, transductive media would become energetically resonant, and all matter would break down into energy - or at least some resonant balance I/e orbit between the two. My real question is, what is entropy? It seems to be what causes matter to transduce energy into forces that affect and are affected by it. So there must be a transducer of energy and matter, because matter would otherwise just polarize itself into a sort of energy-matter semiconductor consisting of the very base of what matter is. Some say hydrogen, some say quarks, some say strings of causal entanglement, and others say pure energy meaning nothing at all but space with or without potential I don't really know. But what is entropy? It turns energy into matter and can therefore turn matter into energy or is sisters with something that can. But how? Why? What even is it, which is a thing that creates matter out of pure space / energy / potential? And it or them that turn matter back into potential? How and why can it have the same rules at both the level of space and nothingness? I'm gonna short a fuse just thinking of this stuff huh?

If you launch the thing at exactly right velocity + direction, you can achieve stable circular orbit with any attractional force. The R^-2 forces are only necessary for stable eccentrical orbits. Achieving that exactly right velocity is hard in practice, though.

[@g4me-time524]

Indeed, you can create an orbit with all kind of potentials, it doesn't need to be 1/r^2. As long as no energy is lost there is no reason for it to fall into the center, when the initial conditions are right.

[@petehiggins33]

This is true but they cannot be called stable orbits. They are unstable orbits where the slightest disturbance will cause the object to crash and burn or spin off into space. Stable orbits such as gravitational orbits can be disturbed ie have their kinetic energy changed and they will just adopt a slightly different orbit corresponding to their new energy.

[@g4me-time524]

@@petehiggins33 @number 33 this doesn't sound physically correct. You can calculate the escape velocity for any kind of potential by integrating the potential towards infinity. So you won't accidentally let it escape the orbit by giving it a small nudge. Similar with falling to the center: unless it hits the object in the middle, the sum of potential energy and kinetic energy will be constant. They may not be circular or elliptical orbits, but they will be definitely be stable in a two body system.

@3:00 Having a spherical system spinning in the center then throw another spherical magnetic by past the center system to see if you achieve an orbit.

[@adamholste791]

What your seeing is it being pushed and pulled at different strengths by the field depending on location and momentum, not partially entering an orbit. Though.. this is an interesting experiment.. the close it is the harder and faster it'll whip n pull.

Isn't centrifugal force a pseudo force?

[@advaykumar9726]

It is

[@C0deH0wler]

There's just the ever change vector of gravity as the object goes around, and very fast 'sideways' velocity.

[@TlalocTemporal]

Centrifugal force is exactly as fictitious as centripetal force. It's just a name for a group of other forces that behave similarly, like pressure, lift, or the normal force.

[@carultch]

@@TlalocTemporal No, that is not true. There is a specific reason why the centrifugal effect is called a pseudoforce, and those other examples of forces are not. The centrifugal effect is called a pseudoforce, because there isn't an interacting pair of objects that cause it. It is caused by one object as a consequence to being in a rotating reference frame, and attempting to travel in the inertial straight line, but having another force constrain it against doing so.

Magnetic field drops by r cube ? I didn't know that, what's the exact equation?

[@idahosgradeafinishesidgafd6292]

I have tried the negative side of an earth magnet and a solid steel pendulum suspended by a rubber band. I guess what I did has a name it was kind of quantum locking or tidal locking. I was using two forces of magnetic repulsion and rubber band retraction. Try this sometime. It gets some velocity and terminates depending on the size of magnet and how hard the band pulls.

Hi action lab ! Similarly can you make 2 electric charge orbit each other?

[@jeevananand4810]

Well yes. Atoms literally have Protons (Positive Charge) & Electrons (Negative Charge) , with electrons orbiting the Nucleus containing Protons.

[@jaikumar848]

[@andricode]

@@jaikumar848 Well you just answered yourself

[@landsgevaer]

@@jaikumar848 And so are the magnets. In an orbital, I mean. Except that they are macroscopic and constantly interacting with other stuff, so classical theory doesn't break down quite so much as for a Hydrogen atom. But apart from that, these orbiting systems are not different in any way. So if you insist that electrons are in an orbital, not an orbit, then so is everything else, in principle. If you don't insist, then an electron in orbit around a proton is a somewhat fair classical model (ignoring radiation losses etc.).

Action Lab, use GPT-3 to generate some video titles based on your channel, like Tom Scott did

[@davidmsf]

I discovered this when I learned to computationally simulate gravitation and decided to play around with the laws involved. The simulation manages to create orbits when it follows the law of gravitation as we know it (inverse square distance), but fails miserably when we change something, collapsing or scattering the simulated objects indefinitely... 😀

[@xeridea]

I remember Super Mario Kart on the SNES, in battle mode on an open course, you could shoot a red shell just right to get it to orbit a player. I was young at the time, this was quite interesting to me.

[@adralestosdragonrider8759]

From what i remember from college physics there is no centrifugal force. if you spin a ball an suddenly release it . It will fly perpendicular to the last position in the circle it was doing. It will not fly away from the center as it would do if there where a centrifugal force as you show in the graphic

[@chairuwu4903]

Work smarter, not harder! If a magnet was spinning, than stable orbits could be possible, because from the perspective of the other magnet, the body it's orbiting is a monopole (of course it really isn't, but in this situation it's close enough).

[@adamwong246]

I think you CAN make them orbit, if you stretch the word "orbit" a bit. Make a big flat surface with a strong magnet mounted in the center. Now build a small robot vehicle- it has 3 "legs" with un-powered bearings for feet, so it can roll in any direction. Then mount a rotary servo on top and to that, attach another magnet. You'll need a sensor that detects the direction of the magnetic flux of the big magnet, so the bot can rotate it's little magnet accordingly to counterattack the sum magnetic forces.

[@Vodkavsky]

Hang on, in the final simulation you had, you were showing the stable orbit, but then the two oscillating orbits which were inevitably going to repeat themselves as they continued circling and then eventually returned to their original position. They trace an outer circle with their many different orbits, so they can still orbit, it would just be repeating or oscillating in a set pattern, rather than a single constant loop in each of their revolutions around their point of orbit. This should mean that they can orbit, just not in the traditional sense, and so long as their orbits don't get changed by external forces, right?

[@DUKE_of_RAMBLE]

I think the best setup for this would've been to use a large spherical magnet, stuffed inside a massive funnel (spout/exit being smaller than the large spherical magnet), and then a smaller spherical magnet. The key ingredient is the final piece: a slow spinning motor to affix the funnel to -- a drill might work best for both its adjustable speed via trigger, and ability to easily attach the funnel via its chuck. It'd take quite some effort, but setting the funnel rotating, then gently tossing in the smaller magnet, I can envision eventually presenting you with a perfect analog. With the funnel spinning fast enough, the rotation and friction on the small magnet will want to be flung out; however, the magnets attraction to each other will counteract the centrifugal effect. _(ideally, I think a small steel ballbearing would be better than the small magnet, to eliminate the pole issue of causing a repelling force every so often; only one attractive body will likely help dial in the rotational speed and "orbital distance".)_

[@DUKE_of_RAMBLE]

It's possible you could also accomplish this by using your low friction surface, directly hooking the large magnet to the motor (drill), and then attaching the small magnet (or BB) to it via.... sewing thread maybe? BUT the length of thread would be longer than the large magnet's magnetic field, allowing the smaller magnet to travel too far if the motor speed is too high (ie 'escape velocity'). My hope in this case being if the speed is "just right", the tether wouldn't be needed.... 🤔Although, then it's a liability, given it's adding weight, friction, and would twist up... Perhaps, then, no tether, but two Plexiglas cylinders acting as barriers to keep it from getting too close, and also going too far. All you have to dial in, then, is the large magnet's rotational speed?
