Some people say that physics is difficult and involves too many mathematical equations.  Is that true?? I always question myself and wonder how I can make this learning more interesting and efficient.

     Although there is no absolute answer for this puzzle, I found that some of the physics principles can be easily understood by carefully observing your surroundings.  For example, if you were hiking in a mountain, which is hundreds meters above the sealevel, how would you feel?  Breathing hard?  Heart beats increased?  That's exactly how I feel too, but have you ever asked yourself why it is so?  Can you reason that from some perspectives of physics? Some physics principles tell us that it is the atmospheric pressure force pushing the air molecules down to the sealevel, whereas there will be less air molecules at a higher level.  Likewise, the atmospheric pressure varies with the altitude, therefore, we would need to breath a little harder than usual to capture sufficient oxygen  for ourselves.  The following cartoon shows how the pressure varies with the altitude.
