It seems to me some of you are struggling because you have tried to learn physics as if it were like mathematics, by memorising algorithms to solve problems.
There is an element of this with physics when applying equations but BEFORE you get to that 'plug n chug' as someone else said, you need to understand what's actually going on at a practical level.
Break up the problem into known and unknown information. The sections of a question lead logically from one part of the solution to the next and so reading the full question gives a good understanding of where the whole question is leading. That will give you clues as to which information is required at the start and you can progress from there.
OP: Can you post two or three questions of the type you struggle with? I will try to give as full an indication of the thought process you need to grasp and replicate for all topics.
