4. The forces
http://iit-jee-physics.blogspot.com/2007/10/study-guide-h-c-verma-jee-physics-ch_23.html

The force chapter is a small chapter. It is indicated in detailed study plan that you can use 7th June to 20th June to revise chapters 1 to 4. Don't waste time. Use the scheduled time to revise all the difficult problems in the four chapters. By revising difficult problems, you will understand the logic of solving those problems. Read the concepts once again. Understanding and frequent recollecting the materials will make it easy for you in the future. Try to do new problems whenever you have time. In the examination, you may not get the problems that you have solved. But solving many problems will give you the confidence and you can solve the new problems given in the examination. You should not fear the new problem. You become capable of solving new problems by solving a large variety of problems.

IIT JEE 2009 Toppers - Planned Schedule is the Key

According to Times India Report dated 26.5.2009, Nitin Jain, the topper said planned schedule is the key to do well in any competitive examination. Listening to tutors and following it up diligently is the trick.

3.9 Change of frame
Ex. 3.10, 3.11
WOE 16,17, 18




Points to Note


The main theme of the section is expressing velocity w.r.t. one Frame into velocity w.r.t. to a different frame


If XOY is one frame called S and X'O'Y' is another frame called S' we can express velocity of a body B w.r.t. S as a combination of velocity of body w.r.t. to S' and velocity of S' w.r.t to S.

V(B,S) = V(B,S')+V(S',S)

Where
V(B,S) = velocity of body w.r.t to S
V(B,S') = velocity of body w.r.t to S'
V(S',S) = velocity of S' w.r.t to S

we can rewrite above equation as

V(B,S') = V(B,S)- V(S',S)

We can interpret the above equation in terms of two bodies. Assume S', and B are two bodies. If we know velocities of two bodies with respect to a common frame (in this case S)we can find the velocity of one body with respect to the other body (V(B,S')


The above expressions for velocity were derived from the relation between position vectors of the body w.r.t. to S and S' and position vector of origin of S' with respect to origin of S.

r(B,S) = r(B,S')+r(S',S)

Differentiating the position vectors with respect to gives respective velocity


Formulas covered in the session

26. r(B,S) = r(B,S')+r(S',S)

Where

r(B,S) = Position vector
r(B,S') = Position vector
r(S',S) = Position vector


27. V(B,S) = V(B,S')+V(S',S)

Where
V(B,S) = velocity of body wrt to S)
V(B,S') = velocity of body wrt to S')
V(S',S) = velocity of S' wrt to S)

we can rewrite above equation as

28. V(B,S') = V(B,S)- V(S',S)

An Intersting Quote from Mark Twain

Yesterday I saw an interesting quote from Mark Twain

I do not allow my schooling to interfere with my education.

This may apply to JEE coaching. If you feel, you are not getting adequate inputs, you have to put in your efforts. Finally, you want a seat in the best institute not they.

So do not allow your coaching institute to spoil your education. Depend on them to a large extent, but listen to your judgement regarding your time table.
