Hi, I am currently working on a computer simulation of free falling objects with air resistance..and I am having problems computing for air resistance..can you give me the formula on how to compute it and an example please?..thank you :))

Usually for free fall problems one would use the Drag Equation (see http://en.wikipedia.org/wiki/Drag_equation" ) to compute the drag force acting on the falling object.

Although in general, there is no "drag equation" that applies to everything.
 
I have no idea the level of sophistication you desire, but the force of wind typically varies as the square of the (wind) velocity as an approximation for flat surfaces.

I have seen some chart data regarding flat areas (boat windage) and wind resistance for varying wind speeds used for calculating the force on a boat anchor. Such data must also be available for wind stress design on high rise buildings.
