The local atmospheric pressure in denver, colorado (elevation 1610 m) is 83.4 kpa. air at this pressure and at 25°c flows with a velocity of 12 m/s over a 2.5-m × 5-m flat plate. the dynamic viscosity is independent of pressure, and for air at 25°c, it is μ = 1.849×10-5 kg/m⋅s. the air density at 25°c = 298 k and 83.4 kpa is 0.9751 kg/m3.

air exerts forces on falling objects near earth’s surface.

explanation:

the term 'free falls' refer to object that are falling towards the earth, in a situation in which gravity is the only force acting on the object.

for an object in free fall, the acceleration is constant (g, the gravitational acceleration), and so the velocity of the object constantly increases.

for objects near earth's surface, there is always another force acting on the object: the resistance due to the air. this force is opposed to the direction of fall of the object, and it is proportional to the velocity of the object, so as the object falls down, this force increases up to a point when it balances the force of gravity, and the object continues its motion at constant velocity (called terminal velocity). since in this case gravity is not the only force acting on the object, we are not in a situation of free fall.

your answer is, orbit around the nucleus

force tends to be low and long diustance masses are high
