"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.

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

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

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

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.

[@Aryaman583]

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]

[@Neet_X-factor]

Yes correct...to conserve angular momentum... angular velocity increased due to decrease in MOI by reducing distance..

[@xlr8_bs514]

@@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.

[@AmitKumar-nq7wk]

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

[@AyushDubey-gf6iq]

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

[@alexanderarchaenius]

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.

[@hamzasaim5912]

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

[@krishivacharya007]

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

[@anishmangla8612]

angular momentum conservation, Iw = constant, on contraction, masses gathers closer to axis of rotation so I decreases so w increases meaning angular speed increases

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

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

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….

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
