Comparing rotational dynamics to linear dynamics again, angular momentum is a property shared by all rotating objects much like linear momentum affects linearly moving objects. This property is a calculation of how tough it would be to stop a spinning object. Unlike linear momentum, however, angular momentum isnt as straightforward with its equation. Youll have to use both math and physical common sense to calculate the angular momentum of objects. Once youve mastered this topic, you will be officially done with the rotational part of this course (of course, well need to use these concepts later on).
Momentum is a vector which describes how difficult it is to stop the translational motion of an object.
Angular momentum is a vector which describes how difficult it is to stop the rotational motion of an object.
For an object rotating about its center of mass, the spin angular momentum of the object is constant, regardless of reference point.
Spin angular momentum, the product of an object’s moment of inertia and its angular velocity about the center of mass, is conserved in a closed system with no external net torques applied.
A torque on an object change’s the object’s angular momentum.
