It sounds like you want engineering, not physics. Physics tries to understand why something falls to the ground, and to make any progress on that problem you have to idealise the problem and neglect other factors (i.e. Air resistance) so you can focus on just one aspect. Engineering is all about understanding which things you have to take into account and which things you can ignore, and what level of precision or approximation is necessary to get you a useful answer.
