Angular and Linear Damping

In this section, we will discuss Angular and Linear Damping in more detail, focusing on the friction properties of physics bodies. Further more, we will discuss physics damping and how this can be used when setting up the constraints for our blueprints. Let's begin by briefly discussing Angular Damping and Angular Velocity/Momentum.

In the realm of physics, Angular Velocity is defined as the rate of change of angular displacement, also known as a vector quantity, which specifies the angular speed or the rotational speed of an object and the axis in which the object is rotating.

In the preceding diagram, we can see that w, or the angular speed, is equal to the velocity divided by the radius of the object that is rotating.

Linear Angular Momentum is proportional to Moment of Inertia (I) and Angular Speed (w), so the basic formula is L = Iw. We now know that w is equal to the velocity and radius of the object, so we can now write the expression as L = I (v/r). Lastly...
