Question

write the Conservation of Angular Momentum:​

Answer 1

$\huge\bf{\underline{\underline{Answer : -}}}$

we have seen the conservation of linear momentum which says that linear momentum of an isolated system is conserved in the absence of an external unbalanced force. As seen earlier, torque and angular momentum are the respective analogous quantities to force and linear momentum in rotational dynamics. With suitable changes this can be transformed into the conservation of angular momentum

Answer 2

Conservation of angular momentum is a physical property of a spinning system such that its spin remains constant unless it is acted upon by an external torque; put another way, the speed of rotation is constant as long as net torque is zero.
