I just want to ask ok weather the formula of linear momentum = moment of inertia x angular velocity is more fundamental or the formula torque equal to moment of inertia x angular acceleration is more fundamental
Is this the same that when we use the variable mass system then we we generally use the formula dp/dt = Force ...
when the mass is constantt it becomes F=ma similarly can we say that L=Iw is more fundamental than torque =I x aplha which can be obtained when moment of inertia is constant
