      "Angular momentum definition, the product of the moment of inertia of a body about an axis and its angular velocity with respect to the same axis." --elinformativo .us
      Sounds to me like angular momentum is from the moving material inward toward the axis, not from the axis upward as shown.

    @OSAS726 3 หลายเดือนก่อน

    This video was very informative and I really loved it. I use what’s called the right hand rule. Cuff your fingers around like you are giving a thumbs up. The fingers point in the direction of rotation and the thumb is always pointing in the direction of either angular momentum or torque depending on which force you are applying this rule. Then once you apply the right hand rule, it’s just a matter of remembering that the angular momentum vector always tends towards the torque vector. There, you have it a simplified way of finding the direction of gyroscopic procession.

      @davidbanner3724 4 ปีที่แล้ว

      I hate to be the bearer of bad news, but gyroscopic precession never occurs when the floor is removed, or the table to set the gyro on, or a pedestal to put a gyro on top of. When none of that is present...the gyro just levels out and stays perfectly still. But you guys know this right? Precession only occurs when the entire weight of the gyro is resting on a table or the floor or a precious pedestal, acting as a fulcrum point/pivot point for the Precession to begin happening. The BOTTOM of the Gyro has to remain STATIONARY, having all of it's WEIGHT on the SURFACE of a TABLE or FLOOR or PEDESTAL for Gyroscopic Precession to even have a PLACE to happen. Wow yall missed that one by a long shot. It went right on by you, it's was right in front of your faces the whole time. Precession doesn't occur without a stationary pivot point at the bottom.

    • @9bananenschalen632
      @9bananenschalen632 4 ปีที่แล้ว

      But, when the girl push a little bit, then angular momentum will have later a different direction and the angular momentum increase so the ring increase the speed and the ring it had more moving energy . And force *distant=energy but the finger doesn't move so we only have the force (the same as the gravity).where does the force come from?????????

    • @juano3000
      @juano3000 4 ปีที่แล้ว

      I do not understand why do you complicate so much explanation.
      It is a simple cross product of resulting vectors.
      The angular momentum is a perpendicular force, resulting from the interacting forces on the ring. When you apply a force, the resulting vector will always be a force in a perpendicular plane to the previous to considered forces. Gyromechanics 101.

  • @davidgronlund3463
    @davidgronlund3463 9 ปีที่แล้ว +2

    When you mention that the axis of rotation always points in the same direction as the angular momentum, I believe it would be more accurate to say that they are usually in the same direction but not always exactly. Intermediate axis theorem (or the less technical name for it, tennis racket theorem) and the nutation of a top are direct results of this inconsistency. Otherwise I think this was great video for beginners and I honestly came out with a better conceptual understanding of gyroscopic behavior under the influence of a torque.

    • @lucashoffses9019
      @lucashoffses9019 8 ปีที่แล้ว +3

  • @Andy-df5fj
    @Andy-df5fj 5 ปีที่แล้ว

    So, gyroscopic momentum induces a precessional torque 90 degrees from an applied torque. Can it be reversed? Specifically, can a combination of applied torques induce a change in the momentum of the gyro? I'm more interested in an increase of rotational velocity, but for the sake of understanding, consider this example: You have a classic spinning gyro suspended horizontally on a string and gravity will induce a precessional torque that will try to make the entire gyro revolve around the string. If you don't allow the gyro to revolve in the direction the precession is trying to make it revolve, will that affect the speed of the gyro? I suspect it will slow down much faster than if it's allowed to precess. Is my suspicion correct?

  • @ZioAlboz
    @ZioAlboz 7 ปีที่แล้ว +1

    Awesome video man, but I am actually confused: I don't think angular momentum is ALWAYS parallel to the axis of rotation. It may have another component that makes the total angular momentum arrow go along another direction rather than the one of the axis. Where am I mistaken?

    • @rontoolsie
      @rontoolsie 2 ปีที่แล้ว

      Generally speaking the direction of L is not parallel to the direction of rotation...hence the need for an inertial tensor. But in special cases when rotation is parallel to one of the principle axes -like a gyroscope ...then the angular velocity and momentum vectors are parallel.

    Really great video!! I loved the explanations!! Your animations are the best on the internet!
    Please more physics videos!

    Great job! This was really helpful. Question though: You say the direction of the angular momentum vector indicated the axis of rotation. Isn't this only true of angular velocity is about a principal axes? If there are products of inertia, angular momentum doesn't have to be parallel with angular velocity, right? Correct me if I'm wrong. Again, thanks for the great animation.

    How do you explain precession by the mysterious right hand rule when it spins in clockwise?

    angular momentum (N m s) and torque (N m) has different units, how did we add those vectors?

    • @EugeneKhutoryansky
      @EugeneKhutoryansky  8 ปีที่แล้ว

      Torque represents how quickly the angular momentum is changing. The units for how quickly the angular momentum is chaninging is (N m s) per second, or just (N m.)

    Could we add two different physical quantities through vector addition

  • @AliVeli-gr4fb
    @AliVeli-gr4fb 8 ปีที่แล้ว

    I have a question, please reply. (around 8. min) when angular momentum is very big compared to torque created by gravity, the rotating object leans just a little. But this gravity always applies this torque every instant, so my understanding is that it doesn't matter how small it is, it will accumulate very fast. So my question is how can a gyroscope stay put for such long time, doesn't gravity act every instant ?

    does the radius of the precession circle increases or decreases overtime, as the rotation speed of the gyroscope disk decreases?

    I always thought that the arrow to indicate torque or angular momentum along the axis of rotation was a notational. I question if doing this was an abuse of notation?

    ถ้าพอเข้าใจแบบเชิงกล. มิติของ ตัว z. มันก็คือ ไบพัด หรือ กังหันนั้นเอง. หรือ เป็น แนวตั้ง. ถ้าเป็นใบพัดกังหันแนวนอนมันก็จะเป็นตัวn ทันที่ ให้ดูแบบภาพ 2-3-4-5-6 มิตินั้นเอง

    Why does the imagined "angular momentum" have that particular handedness direction in relation to the direction of the spin, instead of a handedness in the opposite direction, (i.e. 180 degrees in the opposite direction) ?
    And would it be in the opposite direction if the gyroscope was made of antimatter ?

    • @EugeneKhutoryansky
      @EugeneKhutoryansky  6 ปีที่แล้ว

      It is just a convention as to what direction we want the arrows to point. If we reversed the directions of all the angular momentum and torque arrows in relation to the spin, all the observable measurements would still be the same.

    At 4 minutes, wouldnt it be correct for the F-Vektor to stay vertical as a gravitational force inducing the torque? The way presented in the video there would be a torque and a tranlational movent parallel to the Vektor of the torque.
    or did i get something wrong?

    • @EugeneKhutoryansky
      @EugeneKhutoryansky  8 ปีที่แล้ว

      +ulrike lind, at four minutes into the video, I am not showing the force from gravity, but simply an arbitrary force that someone applies to the object, and then showing how object will react to it. Thanks.
