Everyone read physics concepts ,but few members don't  understand and few members understand very easily. What is difference between this two category members?                 Let's  i explain about these two category members. Few members are not observe surroundings scientifically, they are only see normally means one tree leafs move to and fro. They are observed, leafs are moving that only. Few members are understand very easily, because they are see surroundings scientifically, that means one tree leafs move to and fro. They are do so many questions themselves,  why are leaves  moving ? They will get idea due to air. What is air? again. Air is a mass.what is mass ? Mass is the amount  of matter contained in a body. What is matter? Matter is a substance occupies  some space.What is a substance? So many questions asks themselves. They will easily understand this type of analysis members.     So, observ...
