Why are objects that fall near Earth's surface rarely in free fall? Gravity does not act on objects near Earth's surface. Air exerts forces on falling objects near Earth's surface. The objects do not reach terminal velocity. The objects can be pushed upward by gravity.

its B. i just took the quiz

B. Air exerts forces on falling object near earth's surface.

Explanation:

Free fall: When no external force like air resistance act on the body only gravity force act on the body then we say the body falling freely.

Gravity force : It is that force which act on the center of the body and and body fall towards earth.

Force due to gravity is given by

F=mg

Where

m=Mass of the body

g=Acceleration due to gravity

But when the object that fall near earth's surface then molecules of air exert force on the object. Therefor, air resistance force act on the body near earth's surface.

When the air resistance act on the body then the object that fall near earth's surface is not free fall because both force act on the body force due to gravity and air resistance.

Air resistance force act on the object in opposite to direction of gravity.

B. Air exerts forces on falling object near earth's surface.
