Consider two blocks, one made of wood and the other of lead. They have the same dimensions but the lead is much more massive. If they are dropped and fall long enough to reach terminal velocity, which block experiences a larger force from air resistance?
A) The lead block
B) The wood block
C) The force on each is equal.
D) It isn't important because air resistance can be ignored.

Quizplus · Accepted Answer

Air resistance is proportional to the surface area of the object facing the oncoming air and the object's velocity. The larger the surface area and the faster the object moves, the larger the force from air resistance. The lead block is more massive than the wood block and therefore falls faster, which means it experiences a larger force from air resistance.
