I'm not going to offer an appeal to authority, don't listen to me, look it up.

I didn't read the article so I don't know the context. Inertia is simply how we talk about matter and movement. For example in a spin the heavier the wingtips the more force it will take to stop the spin (wingtip inertia), so the lighter the wingtips the faster you can recover from a spin for example. Lets look at the Corsair, it has fabric outer wing panels and plywood ailerons, the lighter the wingtips the more responsive the airplane will be. The heavier an object is and the faster it moves the more force is needed to slow it down or change it's direction. Bowling ball inertia, airplane inertia, wingtip inertia, you get it.
