Two factors that greatly affect air resistance on falling objects are the
A)size and mass of the object.
B)size and weight of the object.
C)size and speed of the object.

Question

Quizplus · Accepted Answer

Air resistance is directly proportional to the speed of the object and the surface area it presents to the air. The larger the surface area of an object, the more air it will encounter as it falls, increasing air resistance. Similarly, the faster an object falls, the greater the impact it has on air molecules, resulting in greater air resistance. Mass and weight do affect the force of gravity and the rate at which an object falls, but they do not directly affect air resistance.
