Good day to all. I'm working on something that requires me to determine the forces acting on an accelerating vehicle. I have been receiving some prior instruction from someone I know and he tells me that quite simply, an accelerating car would experience forces (1) due to the aerodynamic drag, (2) due to gravity, (3) due to rolling friction and finally (4) a force due to the inertia of the vehicle. I understand the first three quite well but the last one has been troubling me all day. This force, as I'm told, is equal to the product of the mass of the vehicle and its acceleration, as explained by the second law of motion. Is it correct that there is in fact an actual non-fictitious force that acts on the accelerating vehicle that opposes its change in velocity, and thus acts on the opposite direction of the motion of the vehicle? Or if you see something's a miss with what I have here to begin with just hit me up.

I'm trying to develop a simple simulation and I want to get as many of the forces as I can right. Any help would be greatly appreciated. By the way, I'm new here so please let me know if I did anything wrong.
