It seems to me that if you have problems with physics, you need to spend more time studying, and not on your dumb swordsmanship. Just study and don't do your idiocy .. Got it?
Since school, I adore physics and sometimes I ask myself different tasks to perform at a level higher than in other textbooks. Sometimes I can't solve them, but then I turn to the Physics Homework Help and everything immediately becomes clear. And it's not difficult as it may seem, everything is intuitive there, so try it, I think you will like it.
