The terms centrifugal and centripetal forces are the most confued concepts in physics. Let's understand what are centripetal and centrifugal forces and which to use when.
The movement of gears in casting process animation is opposite to what really happens... except that everything is so clear to understand...thank you Sabin
Probably just someone on the animator team not paying attention... but it doesn't make it harder to understand, nor does it detract from the video, so it's not really that big a deal imo
It’s super interesting though. Animation let’s you play God and defy all the rules of logic, let alone physics. I wonder if there are examples in major film productions where the animator unintentionally slipped up? There are millions of examples of the animator intentionally mucking about. Think of that pause in mid air when Wiley Coyote runs off a cliff and has his moment of self-realisation.
Great video. When we get in a spinning ride and “feel” centrifugal force, what we’re feeling is a combination of our inertia trying to carry us in a straight line and the ride deflecting our path to the center (centripetal). That is why it is called a pseudo-force in physics.
woah woah there is science and pseudo science , using the term pseudo to double barrell ANY scientific aspects like pseudo-force is utter nonsense and a clear abuse of language to sooth the pain of the ever growing problem of the many crumbling scientific theories, theories that Schools teach children to believe as real facts.
The centripetal force is the force that applied to the center of the spinning, and the centrifugal force - actually, that the force that applied at the point of centripetal force, but in opposite direction - from center of the spinning outward. If you disbalance those forces, for example, cut the string that holding the spinning object, the spinning object will fly away from the spinning spot. The sport discus thrower is the example - spinning man throwing the discus as like centrifugally accelerated.
@@SpybottleMessuage Sorry for coming in late - I've just found this... If you cut the string the object will continue with the velocity at that time (remember, velocity is a vector and has both magnitude and direction) and travel at a tangent to the orbit in the direction it was travelling at the instant the string was cut. If centrifugal force were real it would travel along a radius away from the centre. Again, the discus travels along a tangent, not directly away from the centre. There is no centrifugal force in an inertial frame of reference. As explained in the video centrifugal force is a pseudo force used to explain observations in a non-inertial frame of reference.The unbalanced *centripetal* force accelerates the body towards the centre of the circle.
I don't know why this was recommended, I don't know why I watched it and now I am left struggling to understand something I previously didn't know existed. This is why I can't sleep at night!
I remember learning about centripedal force. The example demonstrated were weights on a spring sealed in jars of liquid on the end of a rotating plank of wood. It was obvious that the fluid was the dominant force thst pushed the weights towards the centre. So calling it a "pseudo" force feels very appropriate.
As with most such explanations few answer the ACTUAL question people have: why they "feel" a force acting away from the center! This explanation only makes sense in mathematical way. It's very easy, though: Just recognize the tangential motion/force always points outside the orbit, away from the center. Of course you need a force to the side to make the motion a curve. Thats what the video explains in all elaborateness. But look at it the other way. If you have no "anchor"/a force to hold on to like gravitation, a rope etc. the object always moves away from the center (in a straight line 90° to it). And the faster you move the more force you need to apply to not move away from the center. Sitting in a car driving in a bend the asphalt's friction (the "force" to the center) holds the car in line but YOU as the driver move outward basically hitting the inner side of the door constantly as it keeps getting "in your way" on your tangential motion away from the center.
Centrifugal force is no different from the force you feel in a car when it accelerates. The rotating object accelerates towards the center. Of of the key concepts that lead to general relativity was that you cannot tell the difference between acceleration and gravity my measuring it on a single point.
Wow great explanation but another reason might be becoz example ur on a ride with walls attached behind u, ride is moving 360 degrees and Ure acting ur weight on the walls so this force is acting towards walls, something like that ?
Yeah, Something like that. If you throw a baseball in a rotating fashion and then let loose, the ball flies 90° straight away from your arm and not in the direction your arm points. It's like pushing the ball to the side but also changing the direction the whole time whats causing the "centrifugal feel" as if the ball wants to fly in the direction you point with your arm. But at no point is there any push in that direction. The feel is the pull you need to make to change the direction of the ball (which tries to continue in a straight line and so is pulling on your arm). So there is a tangential force outside that rotation - otherwise the ball wouldn't fly and you wouldn't need to pull it to make a circle.
Friction and surface tension in mega orders of magnitude. When you spin something on the surface of water it has vortex and ripples. And if you put something nearby it creates a spin and motion around the vortex no matter what because of surface tension and drag components. Vortex usually get bigger for both because of interaction. Usually vortex never grow. Big Bang is something to do with huge split of two vortex.
I suggest they are the same. It's just a matter of the perspective of the position of the observer. For instance, going around a tight curve, banking the turn forces the vehicle to push against the road. However, at the same time, the road pushes against the vehicle. One being centripetal the other one centrifical, so from an outside observer, he would see both forces as the same. But from the roads perspective and the vehicals perspective, they are different.
3:35 *Somthing to keep in mind for the next video* Gears and casting are both rotating in same direction. They should be opposite. Otherwise, very good explanation and animation
omg thankyou... I was so deep in thought on Newtonian forces, and then bam! Like a car with its high beams on, my eyes are am fixated/stuck watching gears move in physically impossible ways while trying to understand physics!!! haheheh... I immediately scrolled down to see if I was the only one, but you saw it to. Good! I am happy it wasn't the drugs!
CGI is garbage and thats why. Just video a glass of food colored water, its not that hard. I was wondering if the slope of the liquid was zero at the center, but guess what? CGI. Cant trust it.

Thanks for such a clear explanation. I have some questions though. 1) When the tension is released and the object flies off, what direction does it go in? Perpendicular to the radius of the circle at that point because there's no longer an inward force acting upon it to prevent it from obeying Newton's 1st law? If so that would be yet another demonstration that no such thing as a centrifugal force was acting upon it, otherwise it would fly off in the direction opposite to the center. 2)1:41 "More the centripetal force more the object's deflection". If the centripetal force were to remain perpendicular to the direction of motion could it ever be great enough to cause a perpendicular deflection? 3) We know that planetary orbits aren't exactly circular but elliptical. How would you explain this with an animation of the sort you used with the tennis ball?
I’ll make an attempt. 1. Yup, it would fly off following the velocity vector (tangent to the circle at that point). There might be some confusion regarding centrifugal force, it’s perpendicular to both the velocity vector and centripetal force. 2. It won’t be completely perpendicular because the centripetal force cannot cancel off the velocity perpendicular to its direction. 3. It’s because the force of gravity depends on distance. There’s some nice animations if you lookup Keplers equations.
@@horsethi3f Centrifugal force is in the opposite direction to centripetal force, not perpendicular to it. I hope to offer a more precise answer to 2: The "deflection" is the radius of curvature. Any amount of centripetal force can cause a deflection of 90 deg over some period of time. An instantaneous change would mean a 0 radius of curvature, or an infinitely high force.
It's acceleration that's necessarily in the direction of force, not velocity. A car that is braking will be accelerating in the direction of the force, but it's velocity will be in the opposite direction. For a car travelling at a constant velocity, the net force operating on it is zero as the force driving it forwards is exactly cancelled out by the forces of air resistance and friction that oppose it.
No, you wrote the other way, it's velocity would be in direction of force, because object is not turning back due to breaking, and it is accelaration that would be negative (as it retards the car) and change direction.
@@mr.rachetphilanthrophist601 Firstly, it's braking not breaking. Secondly if a vehicle is slowing down, then both the force and the acceleration are in the opposite direction to its velocity as will be the force. What I wrote was the acceleration is in the direction of the force and that is always the case. If the velocity is considered to be positive along the line of travel and the vehicle slows down, then both force and acceleration are negative. However, if the velocity in the line of travel is negative (that is going the opposite direction), then both the acceleration and force will be positive. This all depends on the frame of reference and in which direction along each axis that the displacement is considered to increase. Usually that's drawn as left to right, but that's just convention; mathematically it works either way.
The video gives a nice explanation of centripetal force but it's ruined by the ridiculous statement at the beginning: _"in mechanics we generally see velocity in the direction of the applied force"._ What nonsense! It's _acceleration_ of course, not _velocity,_ that's aligned with applied force (Newton's 2nd law). At any instant the relation between the velocity of a moving object and a force applied to it is completely _arbitrary._
Damn, kids these days are so lucky, I remember when I was a kid. I was scratching my head to understand the clear difference between Centripetal and Centrifugal. This video is so good that if you have interest to learn, you can learn in 15 minutes
As french wrirer Paul Valery wrote once : "you had to be Isaac Newton to say that the Moon continually falls on the Earth, as anyone can see it doesn’t"!
Can you comment on "artificial gravity" by rotation? I I know gravity depends on the mass of the object(s) and said rotation will work in a very limited fashion, and only if the person or objects on the rotating surface are stationary.
I have never considered the surface of the spinning fluid to be curving, but, simply trying to move away from the centre, and being forced up the side of the container because it has nowhere else to go. As the particles move away from the centre and start climbing the walls of the container, naturally, there would be fewer particles in the middle, thus the surface of the fluid drops. What happens when you spin fluid in a bottomless cylinder in zero gravity?
Great visuals. Just need to reverse the direction of the drive gears acting on the cylinder with molten metal. The one depicted is an impossible action-reaction event. Also, "acceleration" is spelled with two e's vice three a's. Minor distractions to a wonderfully simple translation of the target concepts so thanks!
Can you explain to me what will happen when the tennis ball reaches the top and the vertical component of the tension becomes zero. Like why the ball wouldn't fall down? There is no more vertical component
@@minhkhoi8087 that can never happen since the string will be horizontal and there cannot be a vertical component from the tension to balance the weight of the ball.
What does this have to do with in respects of the law of conservation of momentum, because as my understanding has it seems to be the opposite phenomena under similar conditions, is the there a determinant factor for an object’s motion to go outward or inward with the kinetic energy of force applied?
. Are the counterrotating gears in the centrifugal casting animation somehow relevant to what you mean? If those gears were rotating the other way I wouldn't give them a thought, but since you have drawn focus on them by making them appear mechanically counterintuitive I have to think I'm missing something in your illustration. Can you elaborate?
OHH well im 1yr late !!! Anyways watch Centripetal FORCE video by manocha academy!! They have very simpler explanation!! (Im not their PR or something okayy just genuinely saying )
I didn’t understand this centrifugal force when I studied physics in school and now also I don’t understand, except now I’m physics math double major… When I say people that sometimes we can solve physics and math problem without even understanding what’s goin on, they laugh at me. But I’m not going to lie to myself simply because I can solve the mathematical problems related to that topic.. Sometimes, I wonder, is there anyone who really understood this or everyone acting like they have figured it out, just like me..
Wow, this really describes my whole life, down to the electrons circling the nucleus of every atom in my body. And my love life. You know, should I stay, or should I go?
What measurement/term should I use to call the destructive power / force generated by a monkey fist? From what I can tell from the video 4:14, centripetal if the observer is in the influence of the rotating subject, centrifugal if the observer is outside the rotating subject?
When I used to study physics in my school days, understanding these two forces, my brain used to suffer centrifugal forces in outward direction of my skull. 😆
If I understand right, centrifugal "force" is actually the effect experienced by an object being acted upon by centripetal force. It's the physical response of wanting to continue on a straight path, while centripetal force continously forces it to alter direction. Is that accurate?
Pretty much, but keep in mind you will never observe them both at the same time. To sum it up: - If you're looking from the outside (inertial reference), you'll see a centripetal force acting, which is always a result of real forces. - If you look from the point of view of the rotating objects, you'll observe a centrifugal force, a pseudo-force, to compensate the fact that you're a non-inertial reference.
in a rotating cylinder, everything get flung outwards, but the centripetal force is applied by the wall. ib the center there is nothing to give the centripetal force, so it goes outward.
The movement of gears in casting process animation is opposite to what really happens... except that everything is so clear to understand...thank you Sabin

I still don't understand what centripetal force really is
OHH well im 1yr late !!!
Anyways watch Centripetal FORCE video by manocha academy!! They have very simpler explanation!! (Im not their PR or something okayy just genuinely saying )
The force one should employ to maintain circular motion under the appropriate model assumptions.
Force that is required to make the body orbiting a certain radius.
It's determined since you are birthed.
So the spin creates a centripetal force and not all the way around!

What measurement/term should I use to call the destructive power / force generated by a monkey fist? From what I can tell from the video 4:14, centripetal if the observer is in the influence of the rotating subject, centrifugal if the observer is outside the rotating subject?
When I used to study physics in my school days, understanding these two forces, my brain used to suffer centrifugal forces in outward direction of my skull. 😆
Good one
If I understand right, centrifugal "force" is actually the effect experienced by an object being acted upon by centripetal force. It's the physical response of wanting to continue on a straight path, while centripetal force continously forces it to alter direction. Is that accurate?
Pretty much, but keep in mind you will never observe them both at the same time. To sum it up:
- If you're looking from the outside (inertial reference), you'll see a centripetal force acting, which is always a result of real forces.
- If you look from the point of view of the rotating objects, you'll observe a centrifugal force, a pseudo-force, to compensate the fact that you're a non-inertial reference.
Nice video
Ok. Thanks
Thank you❤🌹🙏
in a rotating cylinder, everything get flung outwards, but the centripetal force is applied by the wall. ib the center there is nothing to give the centripetal force, so it goes outward.
