Well, All of the Physics depends on Nature, Natural Phenomena, and Our Curiosity as we developed many applications from that Laws & Phenomena's regularly occurring in nature.
If you'll go to revise just your equations, then i'm sure you'll forget it after an interval of time, so i'd suggest that please learn the concept, try to develop your interest, if you'll succeed in that, then i'm sure remembering your equations would be nothing for you. Good Luck!!
Hope this helps!
