The rate of change of angular momentum is called
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? An abrupt change in torque results in angular jerk. The general case of a rotating rigid body can be modeled using kinematic screw theory, which includes one axial vector, angular velocity → (), and one polar vector, linear velocity → (). From this, the angular acceleration is defined as The time rate of change in angular displacement is called _____. A heavy spinning disk used in many machines in order to conserve angular momentum is a(n) _____. Flywheel. Of the four fundamental forces, which is the strongest? Strong. The man who wrote Principia A body's resistance to a change in its rotary motion is called friction. Moment and rate-of-change-of angular momentum relation: Starting from Newton’s second law, calculating the moment of both sided of the equation with respect to a point O on an inertial frame results in. This resulting relation between the moment and the rate of change of angular momentum is called the moment-rate of change of angular momentum relation (MRCAM). Rate of change is often used when speaking about momentum, and it can generally be expressed as a ratio between a change in one variable relative to a corresponding change in another. 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.

only torques that can change the angular momentum of a system are the external torques acting on a system. The net external torque acting on a system of particles is equal to the time rate of change of the system’s total angular momentum L. 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?
