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
"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.

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......
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 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.
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
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
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✨
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
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.
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.
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
According to Law of Angular momentum conservation IW =constant I=mr² Sir n mass decrease kiya to overall I decrease hoga than angular speed will be increase hogi qki angular momentum is conserved
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 momentum conservation, Iw = constant, on contraction, masses gathers closer to axis of rotation so I decreases so w increases meaning angular speed increases
here angular momentum conservation occur L= IW hota he agar humne rope ko kicha islye masses pass aagaye jisse moment of inertia decrease ho gaya aur angular speed increase ho gai
if mass and angular momentum are constant, than a decrease in radius requires an increase in angular velocity, while the speed of the mass remains constant same speed in a smaller circler means a faster rate of rotation
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
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👍
Body is symmetrical, COM lies on wire . And he pulled hence line of action passes through com . Torque=0 . Hence angular momentum constant. Moment of inertia decreases and Angular speed increase
Angular momentum is equal to moment of inertia into angular velocity due conservation since the moment of inertia decreases angular velocity increases!!
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----------
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)
iska inertia reduce ho gaya because of less mass distribution jiske karand iski angular velocity badh gayi jiske karand iska angular momentum bhi badh gaya

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
@@titanicgamer6804Force due to weight and tension is passing through the axis of rotation hence torque = Fr

The speed is constant but the angular velocity is increased as radius decreased to support the relation ( speed = Radius x angular vel)

When Net Torque = 0, Angular momentum is conserved, so when we decrease the radius, the Moment of Inertia increases thus the angular velocity decreases.

Nope bro….velocity isn’t constant here so we cannot say that omega is inversely proportional to r…

In Radius decrease the angular velocity will increase for conversion of angular momentum 😊
Because omega is inversely proportional to moment of inertia . Aur sir aapne rope khich kr moment of inertia kam kr diya toh usse omega badh gya
One of the best teacher I have every seen you the way you are delivering your in students minds it’s awesome hats off . Faheem Pakistan
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

L= IW = constant, as we pull the thread down I( Moment of inertia) decrease so w (angular velocity ) increased.

Omega to constant hi rahega sir to jab radius kam hogi to balance krne ke liye velocity ko badhna padega
Ang. Momentum is Iw .
If I decreases w increases

For constant Torque, moment of inertia is inversely proportional to angular frequency. When rope was pulled, r decreased,I decreased and W increased

Mass ≠ size my friend. This is relation of axial vectors. You'll learn about it in class 11.
Sigma student for not spoiling the video
Mass distribution distance about rotational axis decreases . therefore moment of inertia decreases .
Amazing video,i have my exam tomorrow and this explanation really helped me,hopefully exam badia jaaega
Yes correct, to conserve angular momentum... angular velocity increased in order to compensate for the decrease in MOI.
According to Law of Angular momentum conservation
IW =constant
I=mr²
Sir n mass decrease kiya to overall I decrease hoga than angular speed will be increase hogi qki angular momentum is conserved
Angular speed is inversely proportional to radius.
He reduces the radius by pulling the string as in the result the speed increases.
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 momentum 😊
Moment of inertia decreases when ball shrinks
Since MOI of hollow sphere is directly proportional to radius ² so, radius decreases, MOI decreses
Moment of inertia inversely proportional to angular velocity
Moment of inertia decreases and therefore angular velocity increases in order to conserve the angular momentum.

The smaller an object gets, is rotational velocity increases. This is why most neutron starts and black homes are spinning faster than stars
Thank u sar aap ham itna achcha chij khate Hain

Conservation of angular momentum. The moment of inertia decreases so the angular speed will increase.
Angular momentum is conserved so decreasing size decreases moment of inertia and increases angular momentum
The guy is handsom❤❤❤
Because of moment of inertia decreases then angular velocity increase
Moment of inertia decrease as most of mass was near the axis of rotation
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👍
Conservation of angular momentum as net external torque is 0 and on pulling the string inertia decreases and thus angular speed increases
thats why neutrons stars are small , but denser than sun , thus having high angular velocity
Body is symmetrical, COM lies on wire . And he pulled hence line of action passes through com . Torque=0 . Hence angular momentum constant. Moment of inertia decreases and Angular speed increase
When moment of inertia decreases the angular velocity increases
