1:39 shadows obey the "reversed" law of rotation :)

[@simon6071]

!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.

Physics Videos by Eugene Khutoryansky I don’t know how the translation editing on KZbin works, but it would have been more appropriate if I was informed that there were some contextual mistakes in my translation so that I can review my translation and rectify what was wrong as it helps me learn from my mistakes because i’m a language learner in addition to being an engineer student. It so disappoints me that a person gets into my translation and alters what he/she sees as right 👎🏽.

[@EugeneKhutoryansky]

TheAdel, I am sorry about this. The way that KZbin subtitle editing works is that anyone can offer a submission, and then anyone can then offer modifications to that submission. 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.

[@johnnyvinje7597]

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 :-)

[@elia8544]

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

+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.

You should do some more videos regarding mathematics, particularly more concepts of calculus

[@jere473]

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]

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.
