I actually posted the exact forumla in the forum thread that FariAnderson posted above. [Here's my post][1]. [Over here I posted some helper methods][2] to calculate various constants based on other given constants.

i searched for a lot of time and make some calculations for all t$$anonymous$$s days, and i figurer out how it wokrs (or the most closelly of it)
bascaally the calc of gravity and drag itÂ´s:
Vector3 GForce = rb.velocity + Physics.Gravity*Time.fixedDeltaTime;
//T$$anonymous$$s wil be our gravity Force applied to the RigidBody
//Similar to rb.velocity += Physics.Gravity*Time.fixedDeltaTime
//but insted to apply to rigidbody we aplly the Drag Force, so:
Vector3 vWithDrag = GForce * (GForce*(Time.fixedDeltaTIme*rb.drag));
//and finnaly we aplly to it:
rb.velocity = vWithDrag;Mon, 24 Jan 2022 19:28:56 GMTNicolasSouza-NIckSDevAnswer by FariAnderson

For what it is worth, I ran into a similar problem when working with Unity's drag parameter. The drag parameter calculation that Unity uses does not seem to behave according to the [Generalized Drag Calculation][1] (w$$anonymous$$ch is fair considering that Unity is a Game Engine)
I resorted to setting the drag coefficient to 0 on the rigidbody and implemented the above mentioned calculation. In addition, I also included [Density of Air Calculation][2] into my drag calculation.
Using the two aforementioned calculations I ended up with a model that corresponded very well with the actual data I had.
