You missed it, like the people who leave at the beginning of the credits and don't see the bit at the end. On the 51st spin it went in a circle, you should watch it again.
Velocity in circular motion is always tangent to the circle. So when we suddenly don't have the forces produced by the edges, that are causing the change in the direction (centripetal force), it just keeps going in the direction of its velocity. It doesn't go in a diagonal (directions A, E) or curve (B, D), but in perfect straight line (C), tangent to the circle, pointing down, as predicted by Newton's 1st Law.
But the velocity is the same always, the speed doesn't change at all, what is the difference before and after taking the edge??? And what does Newton 1st law (inertia) have to do with it, if we apply inertia actually it should keep spinning in the same trajectory.
@@maxvillareal9654 Velocity is a vector quantity, so it has a magnitude (the speed of the ball) and a direction (where the ball is going to). Even if the speed doesn't change, the direction is continuously changing, at every instant of time (why it's circular motion), so we can say the velocity indeed _changes_ (centripetal acceleration), just not it's amount. What does cause this change? The edges! The ball wants to go in straight line, but it's continuously hitting the edge, the edge exerts a force on it, pointing to the center, and makes it slightly change the direction, so it's always in a circle. What is the difference before and after? Without the edge, there's no force to make it change it's direction, so it goes in straight line, at constant speed (Newton's 1st Law). Inertia makes an object at rest to stay at rest and an object in motion to stay in motion, in a straight line. If an object is in a circle, there have to be a force acting on it to change it's course. That's why it doesn't remain spinning or leave in a curve.
@@pedrojorge1912 ow, now I see!!! Thanks a lot. Last question, so in this case 2nd law also applies, right? Because F = m.a, without the edge, no F (excluding friction, etc), means no A, so velocity doesn't change.
The normal reaction is acting as a centripetal force. As the the normal force between the ball and wooden circle becomes zero, the ball goes off along the tangent. This is the observation from inertial frame(inertial frame is a frame which does not have an acceleration, here, it is the camera) But, if we observe the motion from the frame of ball, we would have to apply centrifugal force as a pseudo force (a force that we apply when our frame is also accelerating) to use newton's laws as our frame will be non inertial (an accelerating frame) this time...
I just understood the first 5 lines, the rest sounds like yapping to me, but it's still true. Also I don't get cinematics explanations for this kind of cases, yeah, explains why the trajectory of the ball goes off, but by any other person, what happens in this particular case is that there's no more wood holding the ball so it goes off, as simple as that, no need for vectors anywhere at first sight. I love when this science field seems over complicated, but nah, it's just how it must be (and then I find out it's idealized which means the yapping is stil not enough 😂)
Sometimes, whenever I eat M&Ms, I like to hold two m&m's in between my fingers and squeeze as hard as I can until one m&m cracks. I eat the cracked one, and the one that didn't crack becomes the champion. Then I grab the other m&m, and force it to compete with the champion in this deadly game of m&m gladiators. I do this until I run out of m&m's, and when there is only one m&m left standing, I send a letter to m&m's brand with the champion m&m in it with a note attached that reads: "Please use this m&m for breeding purposes."
Centripetal force is the force always at right angles to the tangential velocity of the ball and always pointing towards the center of the circle that keeps it in circular motion. Centrifugal force is the reaction force at the point where the ball contacts the track and points in the opposite direction of the centripetal force.

Sorry, movement of mass is never "straight" on its own. Space is slightly curved regardless of location, even in deep empty space, and is more curved in other locations such as near small objects, planets, stars, black holes... all due to very complex gravitational influences which permeate the entire Universe and can not be shielded (currently).
Inertia is only for velocity. No body can ever have a memory of its acceleration after the force ceases to exist, since by Newton's second law, force is instantaneous (F =dP/dt).
To explain simply, centripetal force (normal reaction force of the wood circle) keeps it in a circular path. When the circle removed, the normal force is removed so it no longer on circular path and takes the tangential path of the velocity direction at that moment. This is taught in circular motion chapter in 7th grade in my country.

Centrifugal as you are using the blocks as move the ball. It would be centripetal if the ball was used to spin the blocks. (One is a movement a round a ring, the other is spinning around a central point)
The centripetal force is the force that pushes or pulls the object towards the center of the circle. This allows the object to take the circular path. The centrifugal force is the FEELING of continued motion opposing the centripetal force caused by the linear inertia of the object.
@repairshop9549 that is correct. Mass is always flung outward when there is no longer a force pulling it in...specifically, it follows a path perpendicular to the direction of the pulling force at the instant of release. The force pulling the mass in is called "the centripetal force".
For those who dont know Centrifugal force is what comes from inside an object, like a gyroscope providing stability But Centripetal force is when rotary motion is used to defy gravity, or keep something rotating for extended periods e.g. rotating a bucket with water
Centrifugal force occurs when an object is ejected through spinning (like water coming out of a wet ball). Centripetal force occurs when torque occurs due to a force cause a change in direction (like a flail being flung) This is is centripetal force
🤣 and then we are told we live on a spinning ball but yet everything sticks to the outside of it. In reality it’s stationary and the ice wall surrounding the circle of the earth holds the water in. Look at the UN logo and many others. The truth is all around for those who would seek it.
Al salir la bola es fuerza centrifuga. La fuerza centripeta fuerza la bola hacia el centro. Soy Ing. Mecánico. Estos fueron ejercicios que realizamos durante la carrera de ingeniería
Before releasing the ball, the centripetal force is clearly responsible for keeping the ball in its circular path when observed from a fixed reference point, such as watching the video. However, if you were "the ball," you would experience a pseudo force, known as the centrifugal force, which feels as though it is pulling you outward. Once the ball is released, neither the centripetal force nor the centrifugal force acts on it; instead, the ball continues to move due to the conservation of momentum (as stated in Newton’s first law: an object in motion stays in motion unless acted upon by an external force). Upon release, the only forces acting on the ball are negligible friction and gravity, which is counteracted by the table, maintaining the ball's height. Thus, the ball is effectively in a state of pseudo-isolation.

Centrifugal force is inertia limited by a restraining force. Once the restraining force is removed, the object moves in a straight line because, inertia.
If I understand correctly, the word “centrifugal” is actually only inertia, and therefore a mute point, and not a force in and of itself at all. Correct me if I’m wrong about that.

@@RayTheGreat1 centrifugal force is an illusion, there is no force applied away from the center of the circle as this short demonstrates, only the ball going forward and then being redirected by the wooden boundary.
The centreptal motion is converted to a linear motion one the barrier is removed. The balls inertia/centrifugal force carries it away from its circular path once the barrier is removed.
@@Tcmmy131 the wooden boundary defines the displacement of the ball from the center of rotation, the force that the boundary and ball exert on each other is centripetal force, at least in the reference frame of the demo, but really the path the ball takes with reference to the table is not perpendicular the axis of rotation, its more like an ellipse. so that's where the demo breaks down.

I LOVE PHYSICS
Cool toy. I think it works best for showing what centripetal force is. Centrifugal force is something people intuitively understand but a demo of it needs either the audience to be in the rotating reference frame or for the rotating object to be very familiar to the audience specifically because of how it functions with a force that acts similarly to the centrifugal force, like the bucket full of water demo or a literal centrifuge.
@@jimnorth3904Centripetal is a radial force, centrifugal force is a pseudo force, it doesn’t really exist, it’s just the ball’s inertia not wanting to change direction
A push always makes an object move straight atleast for some distance ofcourse shape of object and resistance matters , now keeping this in mind as soon it gets an opening it is moves straight outside mand may be it may take a curve after covering some distance - A LAYMAN VIEW😊
After it plopped out of the circle its none of both, its conservation of momentum. Before it depends on the reference frame you looking at. If we take the camera as reference how we see it, its centripetal force, because we can see accelerating the ball towards the middle of the circle. If we look at it from the balls perspective and rotating with the ball around the circle, the ball seems to be standing still in this reference frame but there is suddenly like a force away from the center pressing the ball towards the circle. Thats centrifugal force. In this reference frame after the ball left the circle, it still has centrifugal force. So stuff doesnt even have to do a circular motion to have centrifugal force. It only depends on if the reference frame is spinning.
I believe that one has a vector aimed toward the center and one has a vector in line with the tangent to the circle. The force isn't an actual thing. It's really just the result of momentum. But the motion of the object is described in the math with those forces.
Strictly speaking, the ball follows a slight curve after leaving the ring. If it didn't rotate around its vertical axis, it would also run straight. Since it has its own rotation it drifts away. This benefits you when playing billiards but makes you bad at shooting.
i watched this until the ball went all the way around, and at the same time i watched 'mudkips - 10 hour edition' it was brilliant use of the working day and i made millions of pounds.
La velocidad que lleva en cada instante es recta y tangente a la circunferencia entonces cuando quita ese elemento la bola sigue esa trayectoria, recta y tangente.
Centrifugal force when its canceled it moved in a straight direction, the forces can be analyzed in vectors and also because of inertia it will move in a straight line
The actual force is centripetal because when you only take in account the ball spinning in the circle, then only forces applied to it are friction and the "normal" force which points to the center.
Acceleration is inward, so when he stops increasing the rotation to pull the piece off the tangential velocity is seen I believe. I also was never good at physics
And also we can tie the thread to one rock 🪨 and spin it then cut at one part then it goes...,.......,.,to some. Where this also one of the example of centripetal force ........
Strictly speaking, the wooden ring is keeping the ball travelling in a circle. When a section is removed, the ball travels along a straight line unimpeded by any outside force. Neither centrifugal nor centripetal force is being demonstrated.
Centrifugal force is the force moving away from the center of the circle- the force the ball exerts on the ring. The force the circle exerts on the ball towards the center is centripetal- the force the ring exerts on the ball.
Centripital:the forced keeping it inwards Centrifugal: the outword expresion of inertia I could be wrong, its veen manybyears since i studied central forces in physics

Centrifugal force is something people intuitively understand but a demo of it needs either the audience to be in the rotating reference frame or for the rotating object to be very familiar to the audience specifically because of how it functions with a force that acts similarly to the centrifugal force, like the bucket full of water demo or a literal centrifuge.
Centrífuga en vez de centrípeta
No, because the centripetal force acts in the tangential direction, while the centrifugal force acts in the radial direction.
@@jimnorth3904Centripetal is a radial force, centrifugal force is a pseudo force, it doesn’t really exist, it’s just the ball’s inertia not wanting to change direction
A push always makes an object move straight atleast for some distance ofcourse shape of object and resistance matters , now keeping this in mind as soon it gets an opening it is moves straight outside mand may be it may take a curve after covering some distance - A LAYMAN VIEW😊
coservation of momentum. at any given point the velocity vector is tangential to the circlen if the circle disappears the ball goes straight
After it plopped out of the circle its none of both, its conservation of momentum. Before it depends on the reference frame you looking at. If we take the camera as reference how we see it, its centripetal force, because we can see accelerating the ball towards the middle of the circle.
If we look at it from the balls perspective and rotating with the ball around the circle, the ball seems to be standing still in this reference frame but there is suddenly like a force away from the center pressing the ball towards the circle. Thats centrifugal force. In this reference frame after the ball left the circle, it still has centrifugal force. So stuff doesnt even have to do a circular motion to have centrifugal force. It only depends on if the reference frame is spinning.
this is amazing I just learnt this at school
This shows that there is no force vector from center to out. It just moves on its own way 😊
The Last direction of speed is Tangent Line of the Circle @ the Broken point.
I believe that one has a vector aimed toward the center and one has a vector in line with the tangent to the circle. The force isn't an actual thing. It's really just the result of momentum. But the motion of the object is described in the math with those forces.
It's the most sciencetific physics experiments I have ever seen!!!
Strictly speaking, the ball follows a slight curve after leaving the ring. If it didn't rotate around its vertical axis, it would also run straight. Since it has its own rotation it drifts away. This benefits you when playing billiards but makes you bad at shooting.
i watched this until the ball went all the way around, and at the same time i watched 'mudkips - 10 hour edition' it was brilliant use of the working day and i made millions of pounds.
La velocidad que lleva en cada instante es recta y tangente a la circunferencia entonces cuando quita ese elemento la bola sigue esa trayectoria, recta y tangente.
Centrifugal force when its canceled it moved in a straight direction, the forces can be analyzed in vectors and also because of inertia it will move in a straight line
Depends on frame of reference. From the inertial frame of reference, the force being applied to the ball by the ring is centripetal.
The actual force is centripetal because when you only take in account the ball spinning in the circle, then only forces applied to it are friction and the "normal" force which points to the center.
Acceleration is inward, so when he stops increasing the rotation to pull the piece off the tangential velocity is seen I believe. I also was never good at physics
And also we can tie the thread to one rock 🪨 and spin it then cut at one part then it goes...,.......,.,to some. Where this also one of the example of centripetal force ........
Centrifugal force, when rotating body moves and when releases it goes towards the tangential direction of the body left.
A good way to study the tangent motion
That was amazing
Advance level: Make it 3-dimensional to spin the ball in a point side down cone. Explain how the speed increase makes the spin ring larger~😊
I keep watching the video again and again and again, seeing when the direction is changed.
Would love a sequel
Very impressive .. ‘Next’ !
Wow, the ball travels in a line tangental to the circle it was moving along??? Thats crazy i never would have thought of that at all.
Well that’s logic! If it “sees” a way out it will go trough that opening
This experiment demonstrates that a sphere always moves in straight path unless some external force is applied.
It's centripetal while the ball is in the circle. Then, the tangential component of the force is greater and it spins tangentially out of the curve
I didn't know it was looping... I've been here for years 🥺
The ball is in centripetal force because when you remove the piece of wood the ball moves outside not inside so it is centripetal force
Strictly speaking, the wooden ring is keeping the ball travelling in a circle. When a section is removed, the ball travels along a straight line unimpeded by any outside force. Neither centrifugal nor centripetal force is being demonstrated.
This when they start to invent pool tabel. Greeting from Indonesia.
WOW, simply amazing that the ball rolls out of the opening........who knew.
Centrifugal force is the force moving away from the center of the circle- the force the ball exerts on the ring.
The force the circle exerts on the ball towards the center is centripetal- the force the ring exerts on the ball.
Can’t help but think of the instantaneous rate of change here.
Beautiful
Awesome!!!
힘은 접선 방향으로 전달이 되네요 😮
Circular motion is the only motion where the direction of acceleration is perpendicular to that of velocity
Centripital:the forced keeping it inwards
Centrifugal: the outword expresion of inertia
I could be wrong, its veen manybyears since i studied central forces in physics
Fiquei até as quatro da manhã. Se nao tivesse que ir trabalhar ficaria um pouco mais pra assistir o resultado disso
如果小球的自旋夠大夠九，它在桌子上的軌道，理論上應該是弧線的，
圓環會讓球旋轉，在桌子上旋轉同時前進會讓球轉彎。
撞球玩家告訴我的😅
There is something similar in a thought experiment about gravity. If the Sun somehow instantly disappeared all the planets would leave their orbits and head off in (mostly) straight lines.
なんの選択肢か分からんまま結果見せられたわ
