      !6:33 "Both the momentum and angular momentum of the entire universe as a whole is always constant."
      Newton's third law of motion states that when one object exerts a force on a second object, that second object exerts a force that is equal in magnitude and opposite in direction on the first object.
      That means vectors of momentum are always created in pairs of the same magnitude but in opposite directions. As a result the net momentum created is always equal to zero.
      Therefore, due to the Law of Conservation of Momentum and Newton's third law of motion, both the linear momentum and angular momentum of the entire universe as a whole must be equal to zero.
      That means the entire universe cannot have a net spin in any direction and cannot have a net linear motion in any direction.
      Nothing outside the universe can change the linear momentum and angular momentum of the entire universe from zero to another value because something that can change the momentum of any part of the universe must be part of the entire universe by definition and that something must also obey the Law of Conservation of Momentum and Newton's third law of motion.

The person who created the modifications did not know who the original submission was from, so he did not know how to contact you about this. I apologize that this happened to you.

    15:58 : In the absence of an external torque, the angular momentum of an object is always constant. Yes out in space, but here on mother earth we have something called gravity and there is some air resistance that will slow down the object that is rotating. The angular veloctity is time dependent, and will slow down due to the friction we have in the air.
    Nice videos, i have been struggling to understand the dynamics in class, but you have opened my eyes. Keep up the good work :-)

      What if the education system implement how the equation was derived and how it is physically or with a model and with vr you can do those stuff more realistically and it's more feasible. I think we need to be taught to experiment and come up with equations with experiments to really understand what the equation is with numbers and you can just use an algorithm to find the best number to fit the equation from other equations of the relevants to find unthinkable equations for more progress

  • @jere473
    @jere473 9 лет назад

    Out of curiosity, it says that it's harder to change the rotation of an object if the mass is further away from the axis of rotation. So if the mass is further away from the axis of rotation then it has a further distance to travel to complete a full revolution? So does that mean that the "wheel" would actually technically move the same amount of distance when applying the same amount of force? For example if it took X amount of force to rotate a "wheel" one complete revolution, then if you increased the distance of the mass from the center of the axis to double it's original length, does that mean the "wheel" would rotate half of a revolution? though still technically traveling the same amount of distance being that the larger wheel now has twice the distance to travel to complete a full revolution?

    • @carultch
      @carultch 3 года назад

      Given two stationary wheels of equal mass (10 kg), which both can be modeled as uniform solid cylinders. Wheel 1 is 0.5 m in radius, and wheel 2 is 0.25 m in radius. Suppose wheel 2 is made from a material that is 4 times the density of wheel 1, to make this possible. We apply a 10 Newton-second impulse to both wheels at a position 0.25 m from the axis of rotation, in the tangential direction. Both wheels are initially at rest, but free to spin on a fixed axis.
      The resulting spin is that wheel 2 will spin four times as fast as wheel 1, after receiving the given impulse. Wheel 1 will spin at 1 radian/second from this impulse, and wheel 2 will spin at 4 radians/second. This is due to the fact that moment of inertia is proportional to radius squared.

  • @physicslover1950
    @physicslover1950 3 года назад

    My mentor this video was great. . But there is a big conceptual problem... The animation at 5:25 where you said that an object in space with no fixed axes of rotation will revolve around its center of mass if hit by another moving object. That object ( big ball - rod - small ball system ) in you video is when hit by that red ball at 5:27 it SIMULTANEOUSLY started translation and spinning about its center of mass.... I know you will now say that because it is a rigid body therefore this is obvious... But wait... What about Einstein's theory of relativity ?
    Einstein's theory of relativity says that enen in a rigid body information can't travel faster than the speed of light ... Then at microscopic scale what cause this spinning because for an object to exhibit spin motion or rotation one needs to apply a force perpendicular to the direction of motion (for example when we tie a pebble to a string and make it orbit in a circular path, our hand provides the necessary centripetal force) ... But in the case of this big ball - rod -small ball system where is the source of centripetal force with counter balances the centrifugal force created by the small ball .... This is so confusing and unintuite that how the staight velocity is transferred to centre of mass. ....... Is there some kind of momentum flow withing the material or a kind of momentum diffusion ? 😵😵..... What happens at the microscopic atomic scale ( material lattice) which makes the whole system to spin Only about its center of mass..... My main question is why centre of mass only... How.... Where does the centripetal force comes form? Is the speed of light and the theory of relativity responsible for this spinning in space..?
    So I will be very very grateful if you make a video on rotational dynamics on the topic of "Why objects in space spin abouttgeir Centre of Mass when they are hit be other objects?
    It would be great if you used the same example of balls and rod.... Or multiple balls and rods....

      +Eugene Khutoryansky An interesting application combining the Universal Law of Rotation
      and Gravity was done by James Watt (1788) in his centrifugal governor. This device is also known as the "Fly Ball Governor" for steam engines. Personally, I found it to be an elegant method of early systems control. Although its original use is considered archaic, the principal is in modern day machines like CVT transmissions.

    Hey eugene, can you make videos on, perpendicular axis theorem, parallel axis theorem, rotational motion, centre of mass and can you help us tackle problems like the 2016 jee advanced exam rotational motion question using intuition

    • @EugeneKhutoryansky
      @EugeneKhutoryansky  4 месяца назад +1

      I will add the perpendicular axis theorem and the parallel axis theorem to my list of topics for future videos. I believe I already covered rotational motion and center of mass in this video. I also have some other videos on these topics in my playlist "Mechanics videos in order" at ruclips.net/p/PLkyBCj4JhHt-EKlWZmoaw9V9-qIDdngm6.

    For some reason, I was always under the impression that hitting something dead-on would apply more in terms of velocity, and that hitting the edge would apply more angular motion but less velocity. So no matter where you apply a force to an object, it's always the same? There's no trade-off?

      Veritasium has an experiment on this. He shot a bullet vertically at a block that was free to ascend, both directed at its center, and off to the side.
      He discovered that the centers of both blocks would rise the same vertical height, just as conservation of linear momentum would predict. The block that was hit eccentrically did spin with more angular velocity, but they both received the same linear velocity as a consequence of the collision.
      Since the collisions were both inelastic, this means that more energy is dissipated in the center shot to the block than the eccentric shot, since the eccentric shot has to also provide the rotational kinetic energy.

    i want to ask something.
    If i rotate an object in space, then the object will rotate continuously forever right?.... so, i think we can create a fake gravity using rotation on the space like the one i saw on "interstellar" movie. suppose we are on the edge of the object which is spinning, we will experience a gravity towards the outside. Then, based on the theory of relativity, we will see the clock in universe is moving slower than our clock, isn't it?

    • @EugeneKhutoryansky
      @EugeneKhutoryansky  9 лет назад +2

      aghaanantyab Yes, the object will rotate forever, and yes, we can rotate a spaceship or a space station, thereby creating the appearance of a fake gravity towards the outside for the people on the inside wall rotating with the spaceship. However, this will not have the impact on the flow of time that real gravity has. For example, from the perspective of a person floating at the center of the spaceship, there is no apparent force of gravity present, and he would therefore see all the clocks in the Universe outside of the spaceship behave the same way as he would if the spaceship was not rotating.
