Yeah, I agree, physics is complete and utter bull**** and completely nonmedical. After all, who uses physics to understand how the heart functions as a mechanical-electrical pump to keep you alive? You'll never use physics, especially not in cardiovascular and pulmonary physiology and understanding how radiology works. The science that forms the cornerstone and basis for all other science disciplines is complete nonsense 🙄
Anyway, to answer your question, physics on the mcat is simpler than that taught in your courses, especially if you happen to be taking calc-based physics. Well, the problems are simpler, but you get less time to solve them so maybe it balances out. Calculations are shorter though, so if you find yourself doing some crazy long mad division or something multistep on the test you are probably doing the problem wrong. Most problems can be solved quickly (if you know how) and with minimal arithmetic, mostly logic and a little bit of guestimation (ex. 9 div by sq rt of 8 is about 3, etc).
