    This one is for all the IGTans who love physics. ;)

    We all know,
    Work = Force X Displacement

    Now, most of us go to sleep on the same bed where we start our day from.
    Therefore, our total displacement in a day = 0. :think:

    Therefore, total work done by us in a day = 0 (ZeR0). :shock:

    This thing came to my mind after recieving a SMS on "Hard Work bla bla bla" ...

    Do you agree with me ??? ... I'll be waiting for your replies ...

    the force aint constant during the whole day and hence you cannot apply this equation .. we have to divide the total displacement into small intervals ..
    let the segment be (delta)X .. and interval i .. so work doen in i-th interval is

    W= [lim (delta)X approaches 0] n(sigma)i=1 F(Xi).(delta)X

    now this can be represeted as integral of the function F(x) between the limits x1 and xn ..

    also when you go far enough and want to come back to bed then the direction fo force has to be reversed .. thus total work increases ...

    dunno how much of this jibberish is correct but in a hurry thats the best i can do ..

    alpha1 I BLUES!

    Finished with my woman cause she couldnt help me with my mind
    People think Im insane because I am browning all the time
    All day long I think of things but nothing seems to satisfy
    Think Ill lose my mind if I dont find something to pacify

    Can you help me thought you were my friend
    Whoah yeah

    I need someone to show me the things in life that I cant find
    I cant see the things that make true happiness, I must be blind

    Make a joke and I will sigh and you will laugh and I will cry
    Happiness I cannot feel and love to me is so unreal

    And so as you hear these words telling you now of my state
    I tell you to enjoy life I wish I could but its too late

    the displacement cannot be zero because if u look at it in a more wider array of events our universe is expanding, and so is our galaxy the milky way. that way the displacement can't be zero cuz as the universe expands , the galaxy expands, the solar system shifts away, and thus our planet moves all ending up with us moving along with this stretch factor.

    Displacement does not mean how much WORK u do per day. It's just how distant are u from ur original position where u started from. (displaced)

    What's physics?? :grin:

    Which Frame are u talking about??

    Everything in Universe is relative..So we consider a Frame. When two trains go side by side with same speed, passenger of one train will see another train is still ...Here the train is frame..

    Think it like that way...

    i'm not talking of it as in frames, i'm just talking in general. If the solar system has moved a tiny bit from it's position doesn't that mean all creatures on our planet moved along with it.?

    I live in the mountains, the rocky mountain, and according to some studies, all of us livin here we are apparently getting 1cm higher in elevation each year.

    thanks for ur opinion, which doesn't matter.
    it's typed as POT HEAD, learn first then pass comments about write or wrong

    Congratulations, youre the first person (i've seen) to take spellings on the internet seriously ....... and then make a spelling mistake yourself.

    btw: Do you understand what a frame of reference is?

  17. basit_jaaaani

    basit_jaaaani I'm gUnnin' fer uuu

    No I do not understand what a frame of reference is.
    but i am very much looking forward to learning about it in college next semester.

    you've got the question wrong .. displacement indeed does not mean how much work but displacement DOES influence the total work done .. the question is
    if starting point is bed and ending point is bed .. then the total displacement is zero .. you see you've come back to where you started from .. you havent displaced in vector terms ..

    now the simple answer to that is that the force is not constant .. and thus this equation does not hold for this particular setup . .we need to break this displacement up into bits in vectors thus giving the force positive value and negative value .. summing up the individual results (or area under the graph) ..

    and this frame of reference thing is correct to some extent .. but then the solution will become even more complex . .the starting point (bed) and the object (yourself) would be moving with respect to a third point withing some frame of reference . .thus comes in the tacky physics .. lets not go there ..

    by the way that write or wrong typo was hilarious .. well caught shs :beer:
