Can you solve these physics riddles? ft Simone Giertz - Part 1/3

heavier one. terminal velocity is reached when drag force from air is equal to force of gravity on object.  since heavier ball is acted upon by gravity stronger than the lighter one or will require greater air resistance to cancel our this acceleration thus reaching terminal velocity.  an alternate approach is that heavier ball has more inertia and requires more force (air resistance) to impede it's acceleration.
