Question

explain conservation of angular momentum of a body performing linear and rotational motion​

Answer 1

Answer:

Just as linear momentum is conserved when there is no net external forces, angular momentum is constant or conserved when the net torque is zero. ... We can see this by considering Newton's 2nd law for rotational motion: →τ=d→Ldt τ → = d L → d t , where τ is the torque

Answer 2

Answer:

Conservation of Angular Momentum

The law of conservation of angular momentum states that when no external torque acts on an object, no change of angular momentum will occur.

Linear momentum is mass multiplied by velocity, so it follows that angular momentum is the moment of inertia, measured in kilogram meters squared, multiplied by angular velocity, measured in radians per second. Radians are just an alternative to degrees.
