The rate of change of linear momentum of a body is directly proportional to the external force applied on the body , and takes place always in the direction of the force applied. so the rate of change of momentum is Force ie ,Newtons second law helps us to derive an equation for force. Consider Torque can be defined as the rate of change of angular momentum, analogous to force. The net external torque on any system is always equal to the total torque on the system; in other words, the sum of all internal torques of any system is always 0 (this is the rotational analogue of Newton's Third Law). Now if the radius is made decrease somehow at some rate until it get's zero, how do I find the rate of change in angular velocity? Also, the angular momentum being conserved, dL/dt=0, ie, no torque acts on it. Yet since the angular velocity is changing, there has to be an angular acceleration. So how can there not be a torque? Conservation of Angular Momentum: An ice skater is spinning on the tip of her skate with her arms extended.Her angular momentum is conserved because the net torque on her is negligibly small. In the next image, her rate of spin increases greatly when she pulls in her arms, decreasing her moment of inertia. It is not always true that torque = I*alpha because the moment of inertia of an object can change. What is always true is that torque = time rate of change of angular momentum.

What is angular momentum? Angular momentum is the quantity of rotation of a body, which is the product of its moment of inertia and its angular velocity. Linear (The rate of change of the angular momentum is, in fact, equal to the applied torque.) A figure skater spins faster, or has a greater angular velocity ω, when the arms are drawn inward, because this action reduces the moment of inertia I while the product Iω, the skater’s angular momentum, remains constant.
