Subhajit Chakraborty Grade: 12


 I am a student of class xii and just finished the "Rotational Mechanics". I have Two physics books and solved almost all the problems in these books ( One is of cource H.C.VERMA ) . I found that we have to use generally conservation of momentum, Formulas of mechanics , Conservation of Energy and Formulas of this chapter . But Which one should be used where is not totally clear to me. I know that where the external force is zero we use cnservation of momentum , and some other cases where the rest is used. But it is not always helpful. 

 Respected sir , you are experienced enough and may know some tricks to understand the problem and visualize its solution. I am not asking How to solve them but how to clear the  mist. Thank you for your valuable time.
