... Inertia is a measure of an object’s RESISTANCE to CHANGE in state of motion. (Things—like people—don’t want to change!) The word inertia comes from the Italian word for “laziness.” Inertia is DIRECTLY PROPORTIONAL TO MASS ONLY. (More mass means more inertia.) Inertia has nothing to do with size, spe ...
