Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The upward force on an object falling through the air is ____
A
air resistance
B
momentum
C
inertia
D
gravity
Explanation: 

Detailed explanation-1: -Air resistance is the upward force that resists the motion of a falling object. The amount of air resistance depends upon the speed of the falling object. As an object falls faster, the amount of air resistance increases.

Detailed explanation-2: -The force of air resistance is approximately proportional to the speed of the falling object, so that air resistance increases for an object that is accelerating, having been dropped from rest until terminal velocity is reached. At terminal velocity, air resistance equals in magnitude the weight of the falling object.

Detailed explanation-3: -Common Questions about Air Resistance Air resistance happens when an object moves through the air. Depending on the velocity, shape, and area of the object, resistance differs. The faster an object moves and the greater its area, the higher the air resistance gets.

Detailed explanation-4: -Air resistance is, basically, friction. Friction opposes the motion of an object moving through/on a medium. In this case, the air is opposing the motion of something moving through it. Air resistance only acts upward, opposing direction, for an object moving downward.
