Objects falling through the atmosphere will experience turbulent flow and be subject to drag depending on their drag coefficient. They will be travelling too fast to experience laminar flow or viscous friction.
In turbulent flow the aerodynamic drag force F can be found from the equation
F = 1/2 x (density of air) x (velocity of object)squared x (Frontal Area) x (Drag Coefficient)
If an object falls far enough, it will achieve a velocity where the drag force is equal to the gravity force (m x g), and it will then have achieved its terminal velocity. This is experienced by skydivers, but they have the option of varying their drag coefficient by the attitude adopted, ie headfirst with arms and legs tucked in, or with body horizontal and arms and legs extended, so can vary the terminal velocity.
Objects falling through air experience a type of fluid friction called air resistance.
Objects falling through air experience "air resistance". Also referred to as "drag", the resistance is dependent on the speed of the object and the surface area exposed to the airflow.

True
Air Resistance or Drag is the type of friction that a falling object encounters while in the air. It has three classifications which are the lift-induced, the parasitic drag and last the wave drag.

Air Resistance: a form of friction.
There is something called "air resistance" or "friction".
Aerodynamic drag force, equal to: velocity2 * objects drag coefficient
Air resistance
To be very technical and precise, the answer consists of two parts: 1). No. 2). Outside of laboratory conditions, there can be no free-falling objects on Earth. "Free falling" means that there is no other force on the object except the gravitational one, so there's no friction acting on it. But this situation is impossible on Earth, because anything that falls is falling through air, so it does have friction acting on it ... called "air resistance" ... and it's not free falling.
