To be honest, the application of maths in a-level physics for AQA physics is pretty much non at all...simple standard form, maximum is x10-9 so far and also simple re-arranging of formula. Thats all ive encountered so far but i know ill be doing vectors and other mechanical aspects come module 2.
Those who say they find one subject easier than another, this could be due to personal capabilities e.g. if ur a maths genius ofc ur gonna find maths easy...but also the teachers themselves. They play such a huge role in your attitude towards the subject. Horrible teacher, horrible attitude thus you feel you cannot handle it. I personally, prefer chemistry to physics. Why? Because i feel that when i do the content i seem to naturally be able to grasp it and understand it faster than i do for physics. Both my teachers have superb attitudes towards their subjects, espically physics teacher that will go on about a particular aspect of physics such as when we asked him if superman could really fly at the speed of light lol.
But as others have mentioned, physics isn't meant to be hard if you apply yourself and take time to understand the fundamentals. Without the bricks you cannot build a house, same for everything in life. Can't run until you walk.
However, must agree that the content is getting 'dumbed down'. Big wake up call from what ive heard from the january 2008 A-lvl exams. People were really blown away by new wording and how they approached questions such as naming axis on graphs. To be honest is the new people who have replaced the old people who wrote the tests and moved onto new syllabus (spelling i know :P). BRING THEM BACK I SAY FOR JUNE 08 ;P
