Sahi to h There is no external torque, as the thread itself is the axis. Hence I¹w¹ = I²w² As the size of ball decreases, it's Moment of Inertia(I) decreases, and Omega (w) increases
Angular momentum conservation(Iw=constant ,when Fext=0)!!!!!!after he pulled the lower string ,the distance of the adjoining parts from COM reduced i.e. MI decreased, thus angular velocity increased in order to conserve the momentum.
@@bhaskar1157 Nahi woh galat ha, aisi nahi karte kyuki linear velocity constant nahi ha. When Net Torque = 0, Angular momentum is conserved, so when we decrease the radius, the Moment of Inertia increases thus the angular velocity decreases.
Angular Momentum Conservation L = Moment of Inertia x Angular Velocity Mass gets concentrated near centre of mass, so moment of inertia decreases hence angular velocity increases
Apke jese sir agar har schools or cllg me ho to asani se ham india me education leval high kar sakte hai ...... apke jese teacher hajaro scientist bana sakte hai. 😇🤞
"Conservation of angular momentum". It states that the total angular momentum of a rotating body is conserved in absence of torque(T=0). i.e., L=mvr=constant. Since the radius of the body decreased the linear velocity of the body increased.
L=Iw According to conservation of angular momentum Angular velocity is inversely proportional to moment of inertia When he pulled the string downward it reduces moment inertia which causes to increase angular velocity
When moment of inertia decreases by pulling the string downward then to conserve law of conservation of angular momentum the angular velocity increases.Formula:I1w1=I2w2
Linear velocity is equal to angular velocity and radius multiplication.When radius decrease ,angular velocity increases when radius increases, angular velocity decrease but the linear velocity remains constant 😊 like if agree with me
😊😊Sir mene jese socha tha same wahi tarika aapne apnaya or mene ye har video me notice Kiya h jese mene socha tha wese hi aapne bataya यानी same thinking 🤔🤔🙏🏻🙏🏻🙏🏻
Instead…the omega is increased because of angular momentum conservation as no external torque is applied to the system and IW=constant so as I(moment of inertia decreases….W (angular velocity) increases….
@@lakshmisinghal4816shi h lekin..... Torque external nhi hota puri body ka torque zero hoga because there is no perpendicular torque on system so torque of body is zero than angular momentum is conserved......
Angular Momentum of this system will remain conserve as we haven't applied any external torque. Since Iw= constant; radius of sphere gets decrease when we pull the rope and hence I reduce and w will increase.
L = mvr For constant Angular Momentum (L) (means no torque is applied), tangential velocity (v) is inversely proportional to the radius (r). This is why you decreased the radius which led to an increase in tangential velocity.

Angular momentum= mass× velocity× radius. So angular momentum is directly proportional to radius and radius is inversely proportional to velocity, which means if you decrease the radius ,velocity automatically increases because mass is constant here. He just decreased the radius of whatever this thing is by pulling the thread and speeding it up
In the first Arrangement the masses are far away from it's axis of rotation, Compared to second arrangement Due to which the moment of inertia of the system is higher in first arrangement And less in second arrangement , As it is demonstrated in the video, he gave the angular velocity to the first arrangement and then shrink the volume of the first arrangement ( So that all the masses come closer and thus the distance from the rotation of axis decreases) so that the moment of inertia decreased therefore to conserve the angular momentum( Because there is no net external torque applied during the motion), omega increased
Conservation of angular momentum bc the moment of inertia decreased bc the radius of the shape thats close to a hollowsphere decreased so to conserve angular momentum rotational speed should increase
here radius from axis of rotation decreases so moment of inertia (I) also decreases as I = 2/5mr^2 now to conserve angular momentum omega should increase itself so rotation in sphere speed up
Radius is inversely proportion to omega(w) (that is angular velocity) When you pull the rope its radius is decreased that's why the angular velocity is increased
Angular velocitu is inversly propotional to the radius.... When radius is decrease by pulling the string below that toy the angular velocity increases becuse radius is decreased👍
In daily life situation: children in villages play with a thin thread one end tie a knot to index finger on left hand and the other end to the right index finger. the cap of bottles is holed at centre flatened and is placed at middle of thread(the thread passes through the hole) and the thread is rotated to 2-3 times a round and while they are rotating circularly the left hand is pulled to left direction and right hand to right then it rotates first enough(the speed is very fast it may cut a small pieces of plants) and won't stop until we stop pulling it 🙂
Conservation of angular momentum ... moment of inertia decreases when mass comes nearer to axis of rotation and for conservation of angular momentum angular velocity must be increase .i.e Iw=constant
Radius is inversely proportion to omega(w) (that is angular velocity) When you pull the rope its radius is decreased that's why the angular velocity is increased -----------IS IT COREECT----------
Uska chota krne se uska moment of inertia bad jata h or inertia badne se angular velocity km hoti h angular momentum ko conserved rakhne ke liye kyuki us ball per koi ext. Torque nhi lag rh h
external torque about its axis is zero,hence angular momentum will be conserved,initial moment of inertia jyada but omega kam,nichle string ko kichne se moment of inertia kam hoga jisse omega badha ga bcoz angular momentum is const.
angular momentum conservation, Iw = constant, on contraction, masses gathers closer to axis of rotation so I decreases so w increases meaning angular speed increases
Momentum (P)=Mass(m)×Velocity(v) P=m×Radius(r)×Angular Velocity(ω) P=mrω So, to conserve the momentum of the body, that is to keep it constant, ω will increase if r decreases.
As (inertia=mr^2) when we decrease radius inertia also decreases And by relation (angular momentum=inertia and angular velocity) when inertia decreases then angular velocity (w) increases to make eq constent.
Well I am a 10th grader and I just passed my ninth, according to me,as the momentum is the product of velocity and mass , and we know that any two quantities that are in product so they have inverse relation p,as you decreased its size , it's velocity automatically got a rise
As we know that moment of inertia and angular speed depends upon the distribution of mass as we can see that, initially the mass was distributed far from the axis of rotation and when the distribution of mass comes near to the axis , the moment of inertia decreases and the angular speed increases this is the law of conservation of angular momentum❤ Thanks✨
During the initial rotation if we reduce the size of that object from the centre of the object the speed will be increase. Reducing the size of an object takes less energy to rotate and then rotate with increased speed. I think so.
Its conservation of angular momentum Angular momentum =M Inertia × Angular Velocity And M inerta=mass×radius square When the thread is pulled the radius of varius masses decreases from the axis around which it rotates and hence the moment of inertia decreases now the system has to increase the angular velocity to conserve the momentum and thats why its speed increases
Angular momentum is equal to moment of inertia into angular velocity due conservation since the moment of inertia decreases angular velocity increases!!
Law of conservation of Angular momentum (I₁ω₁=I₂ω₂) Moment of inertia decrease ho jaega or angular velocity increase ho jaegi (moment of inertia isliye decrease ho jaega kyo ki radius of sphere decrease ho jaegi)
Angular momentum conservation L=Iw Since we pulled the thread the radius in which the mass was distributed decreased which ultimately decreased the moment of inertia (I) hence any external torque was not provided the angular momentum must be constant for that body so the angular velocity increases so as to keep the product (Iw) constant ... Mai itna bhi khass nhi......😅

The speed is constant but the angular velocity is increased as radius decreased to support the relation ( speed = Radius x angular vel)
Angular momentum conservation(Iw=constant ,when Fext=0)!!!!!!after he pulled the lower string ,the distance of the adjoining parts from COM reduced i.e. MI decreased, thus angular velocity increased in order to conserve the momentum.

For constant Angular Momentum (L) (means no torque is applied), tangential velocity (v) is inversely proportional to the radius (r).

Moment of inertia decreases when ball shrinks
Since MOI of hollow sphere is directly proportional to radius ² so, radius decreases, MOI decreses
Demonstration by a Hoberman sphere. What a simple beauty !!! ❤
Sigma student for not spoiling the video
Angular momentum depends upon size of the object.
Thus when the size decreases the rotational speed of the object increases.🤠❤️

here radius from axis of rotation decreases so
moment of inertia (I) also decreases as I = 2/5mr^2 now to conserve angular momentum omega should increase itself so rotation in sphere speed up

The smaller an object gets, is rotational velocity increases. This is why most neutron starts and black homes are spinning faster than stars

Angular momentum ke Karan...
Area decrease karne se speed increase ho jati hai....👍👍
As (inertia=mr^2) when we decrease radius inertia also decreases And by relation (angular momentum=inertia and angular velocity) when inertia decreases then angular velocity (w) increases to make eq constent.
Conservation of angular momtum because Tork is zero so integration of constant is zero hence angular momentum=constant
Ang. Momentum is Iw .
If I decreases w increases
Conservation of angular momentum as net external torque is 0 and on pulling the string inertia decreases and thus angular speed increases
Well I am a 10th grader and I just passed my ninth, according to me,as the momentum is the product of velocity and mass , and we know that any two quantities that are in product so they have inverse relation p,as you decreased its size , it's velocity automatically got a rise
Mass ≠ size my friend. This is relation of axial vectors. You'll learn about it in class 11.
Low of conservation of angular momentum, i1w1 = i2w2 inertia decreases so womega increses
Conservation of angular momentum. The moment of inertia decreases so the angular speed will increase.
As we know that moment of inertia and angular speed depends upon the distribution of mass as we can see that, initially the mass was distributed far from the axis of rotation and when the distribution of mass comes near to the axis , the moment of inertia decreases and the angular speed increases this is the law of conservation of angular momentum❤

During the initial rotation if we reduce the size of that object from the centre of the object the speed will be increase. Reducing the size of an object takes less energy to rotate and then rotate with increased speed. I think so.
V=rw now if v is costant then w inversely proportional to the angular velocity so if radius decreases then angular velocity increases.😊
Its conservation of angular momentum
Angular momentum =M Inertia × Angular Velocity
And M inerta=mass×radius square
When the thread is pulled the radius of varius masses decreases from the axis around which it rotates and hence the moment of inertia decreases now the system has to increase the angular velocity to conserve the momentum and thats why its speed increases
Angular momentum is equal to moment of inertia into angular velocity due conservation since the moment of inertia decreases angular velocity increases!!
Pivoted body , angular momentum
Law of conservation of Angular momentum (I₁ω₁=I₂ω₂)
Moment of inertia decrease ho jaega or angular velocity increase ho jaegi (moment of inertia isliye decrease ho jaega kyo ki radius of sphere decrease ho jaegi)
Angular momentum conservation
L=Iw
Since we pulled the thread the radius in which the mass was distributed decreased which ultimately decreased the moment of inertia (I) hence any external torque was not provided the angular momentum must be constant for that body so the angular velocity increases so as to keep the product (Iw) constant
... Mai itna bhi khass nhi......😅
Angular speed = velocity/radius
Less the radius of sphere (object) more the angular speed
Moment of interia decrsed,so angular velocity will increase dur to conservation of angular momentum
Conservation of angular momentum
R1>R2 then V2>V1
Radius decreases moment of inertia also decreases aur angular velocity increases
Moment of intertia decreased!!!!
Then same angular momentum is giving more angular velocity
Moment of inertia decrease when it bends and angular velocity increasea
When moment of inertia decreases the angular velocity increases
Since radius is decreased i,e moi increase and ultimately angular acceleration increased and Omega will increase
Angular momentum is conserved I. e IW= constant. If moment of inertia decrease angular velocity increase
For constant Torque, moment of inertia is inversely proportional to angular frequency. When rope was pulled, r decreased,I decreased and W increased
Student to bahut cute hai yaarrr😂❤❤❤
Ans: moment of inertia decreased therefore angular velocity(omega) increased hence speed increased
Conservation of angular momentum because moment of inertia decrease so angular velocity increase
