It must be air resistance (sometimes called air friction). Inertia is NOT a force. Weight is the specific name for the gravitational force on a massive object.

That depends on where the object is falling. Is it falling through air? Then there may be three forces acting on it. First is the gravity that makes it move downwards, second is the air resistance that is opposite to the force of gravity and finally the wind. The wind may be from any direction.
And if its falling through a space where there is no air or any other medium then only a downward gravity force acts on it and it keeps gaining velocity indefinitely towardes the source of attraction.

The second would be Drag (or wind resistance).
Newton reasoned that two objects of equal mass would fall at the same rate in a vacuum (in the absence of air), but in 'real life' a feather and a ball of the same mass fall at different rates because they experience different amounts of drag. There are equations to calculate drag, allowing the computation of properties like the terminal velocity of an object (its maximum speed falling in air).

Resistance

Centrifugal rigidity is brought about by using being in a rotating reference physique. Say I watch somebody on a merry-go-around. I see them going around in a circle. For something to go in a circle it desires a rigidity pulling it in direction of the centre, centripetal rigidity. there is not any opposite rigidity, simply by fact if there replaced into then it could be comparable to having no rigidity and the item might go in a in the present day line. (undergo in concepts that turning is acceleration, in spite of if the cost continues to be an identical, and acceleration demands unbalanced rigidity.) Now say i am going and trip the merry-go-around and close my eyes. i will think of of myself as sitting nonetheless, not likely around in a circle. yet i will sense that i'm being flung outwards, centrifugal rigidity. it somewhat is extremely 2 diverse techniques of staring on an identical subject. the two are the two valid.

Possibly inertia?
Air friction?
