physics formula

hello im new to unreal engine and im doing a junior project in physics explaining how physics is implemented into video games and i think that first person shooter template is a great place to start as projectile motion and unit collision is very well shown and i would like to ask where are the formulas written in the code so that i can show to the class. so pretty much where in the code can i find the formulas through which the physics are applied.
Thanks in advance
