Free fall
Air resistance
500 metres per second.
the constant speed that a freely falling object eventually reaches when the resistance of the medium through which it is falling prevents further acceleration.
it spreads out more or becomes bigger thus creating greater resistance when falling threw air
Gravity is one, and I believe that friction is the other. Friction here being caused by the resistance to motion of the fluid the object is falling in. Generally this is termed air resistance or drag and it is related to the object's velocity and cross section as well as the fluid's viscosity.
Air resistance
Just like any other source of friction, air resistance effectively results in a force opposite to the object's motion. If the object is falling, then the force is upward.

Inertia is the resistance of a object to change in its motion

It reduces the acceleration of the falling object due to friction.

The mass of an object will not affect the time it takes for it to reach the ground from a fixed height. Backspace
motion of free falling object does not have friction, while motion of the cart has force of friction
