Which of the following has more inertia, bowling ball or tennis ball, hammer or feather?

My answer would be a bowling ball. The rule for inertia is

Mass is that quantity that is solely dependent upon the inertiaof an object. The more inertiathat an object has, the more mass that it has.

Given that rule, if the Bowling Ball, Hammer, Feather, and Tennis Ball were all the standard size, the answer would have to be the bowling ball. MEYBE
