Question

What is the relation between torque and angular momentum?​

Answer 1

Answer:

So, torque is directly affecting the angular velocity of a spinning object. Since torque can change angular velocity, and the amount of angular momentum an object has depends on its angular velocity, it makes sense that torque can change angular momentum this is how the two are related.

Answer 2

So, torque is directly affecting the angular velocity of a spinning object. Since torque can change angular velocity, and the amount of angular momentum an object has depends on its angular velocity, it makes sense that torque can change angular momentum this is how the two are related.

Newton's 2nd law relates force to acceleration. In the angular version of Newton's 2nd law, torque τ takes the place of force and rotational inertia takes the place of mass. When the rotational inertia of an object is constant, the angular acceleration is proportional to torque.
