# Air resistance in projectile motion

Good morning mathematicians,

I would like to ask you for good resources for modelling projectile motion under air resistance. I have not been able to find any good sources.

Thank you in advance.

• Do you have a specific type of object in mind? A bullet? An airplane? Jan 28, 2019 at 8:06
• @Matti P. I would stick with bullet or sphere to maintain it simple. Because plane would be too complicated object for me I guess, yet. Jan 28, 2019 at 8:15
• Well, a good starting point is to consider the aerodynamic drag of the object. After that, the question comes to setting the value of the drag coefficient $C_D$. en.wikipedia.org/wiki/Drag_(physics) Jan 28, 2019 at 8:23
• @Matti P. I guess that a decant amount of physics background is required like understanding of magnus effect when deriving and modelling the equations? Jan 28, 2019 at 8:26
• It all depends on what your requirements are for the model - or how sophisticated model you want. But I would say that if you have the lift and drag coefficients (if the object does not generate any lift, or is essentially not an aircraft, then $C_L=0$), you already have a pretty good model. Is the object spinning during its flight? Jan 28, 2019 at 8:30
