Inertia by James Nichols published on 2014/01/27 02:16:31 +0000 Call it what you will; I will call it Inertia. 98 layers of sounds in this track! Most I think I've ever had tho many are small. Inertia is the resistance of any physical object to any change in its state of motion (including a change in direction). In other words, it is the tendency of objects to keep moving in a straight line at constant linear velocity. The principle of inertia is one of the fundamental principles of classical physics that are used to describe the motion of objects and how they are affected by applied forces.
