Questions in this category that include the words "This graphic shows..."
or some such, frequently fail to include any graphic. When no graphic is
included, it must follow as the night follows the day that no physics is pictured
in the scene. Inertia is a very popular subject, often appearing in scenes
where physics is pictured. Sadly, however, in an environment that is totally
devoid of graphics, projectiles and the inertia they carry are seldom to be found.
