Hello everyone! I really need your help with something: I really want to study physics, and I'm currently working through a Soviet physics textbook edited by Landsberg. It's a very thorough and fairly famous textbook, but sometimes I find it very difficult to understand certain formulas. I don't want to just memorize things - I need a deep and, ideally, intuitive understanding; without that, I won't be able to move forward.
Right now I'm studying kinematics. With some difficulty, I managed to understand the formula s = at²/2 (at/2 is the average velocity, which you can multiply by the time of travel to get the distance covered - although even that explanation isn't great; I want to understand the essence of all the relationships more deeply). But the formulas derived from it - v = √(2as), s = v²/2a, a = 2s/t², and t = √(2s/a) - have been eluding me for days now.
I've watched many YouTube videos and tried asking several AIs, but nothing helps. Everywhere I just get dry algebraic or geometric derivations of the formulas.
I'm asking for help understanding these formulas, and I'd also love it (that would be absolutely wonderful) if you could tell me how to deal with such difficulties in grasping physics. Thank you so much in advance!!!
