(As I have mentioned in my previous posts, it really doesn't matter much which study material you use.. Just decide any one thing wisely, and do it completely.. It's totally useless to compare two random books.. Just pick up any one thing, have faith in it and complete it..)
Half of the student population consider physics analogous to mechanics! Even I did (I still do).. But it's correct also.. Mechanics is to physics is like heart is to body.. Really! So, I'd suggest to prepare mechanics VERY strongly. You have no idea how great it'll be for you being sound in mechanics. Pick out any chapter and you'd find mechanics in that! Anyways, I now hope you understand the importance of mechanics..
So coming to the tips on how to prepare it.. Generally when people start mechanics, they just want to always skip the basic and easy things and want to reach the advanced mechanics portion.. That's just so wrong.. In fact give more time to the first one or two chapters, that is vectors and motion in one dimension.
It'll seem easy but don't try to do it fast. Have patience and practice a lot.. Advance slowly and steadily no matter what anyone else is doing.. Then comes Laws of motion- the heart of the heart itself.. The key to mastering is doing all kind of different problems, as much as you can. Don,t stick to one type of problems. More variety in LOM problems, more stronger you'll get.
I'll suggest you to do a question bank of approx 200-300 problems based on kinematics and LOM after you complete LOM, and then only advance to work,energy/gravitation/rotation! Clear more and more basics.. NEVER LEARN ANYTHING IN MECHANICS.. Infinite problems can be made in mechanics and only your basics can save you. Try to imagine the problem practically in your brain.. That really helps. And I am saying again stick to basics.. Don't try to be over smart! No matter how hard the problem seems, it IS solved by applying basic fundamentals 3-4 times rather than applying a complex relation 1 time.. I hope you'll are getting it.
After that its work energy and power. Its easy.. But remember to practice work energy theorem and energy conservation problems in bulk.. Do as much problems as you can.. It'll be good.
Then coming to Centre of mass/collision- Here learn the centre of masses of geometrical objects by heart.. They're useful. And pay attention to inelastic collisions. They're tricky.
Its then Rotational motion.. I consider it tough in mechanics (according to me! It can be easy for you).. Mastering this chapter, needs good imagination power.. Try to visualize the motion, torque, friction and everything and keep applying appropriate formulas. REMEMBER the moment of inertia of all basic objects.. Its very important.. Rotation in inclined planes and relative motion are tricky. Understand them well.. Gravitation is easy.. Not much visualisation, just remember the formulas and direct application problems are found.. Sometimes advanced problems from Keppler's law are made. Just remember all formulas!
And afterall, mastering anything needs practice and especially mechanics. Its not a one day wonder. It'll take time.. And it's upto you whether you give it or not!
I may have missed many things but you can always comment or mail me!!!

If you don't know calculus right now, learn the basics of it.. like basic differentiation, basic integration and spend time identifying the problems having calculus involved like rate of change types and all.. rest all you'll learn while practicing questions. u can't be just perfect without practicing.. do mistakes, look for different types of calculus problems and just do them! gud luck
ReplyDeleteDon't let anything come in ur way! good luck..
ReplyDeleteFrost I find physics very tough and i dont understand the way my teacher brings it forward...i really want to crack JEE....what do u suggst i do?
