    Solve World Physics Olympiad (WOPHO) Problems Together

    there are man who r solving...well have you solved moscow olypiads problems from the book krotov

    on the other side

    Kinetic Energy Paradox: What Went Wrong?

    how is he behavior of ground different in both case
  4. P

    Kinetic Energy Paradox: What Went Wrong?

    and if he calculates that then he can boldly say that there is fault in the kinetic energy therom

    Kinetic Energy Paradox: What Went Wrong?

    but i am again stuck up how will paul conclude that he is moving with 100?

    Parallel plate capactiors otherside plate

    how can it be proved that the otherside of the charged parallel plate capacitor has some charge on it

    Kinetic Energy Paradox: What Went Wrong?

    well it depends whether the car has passed paul or not ...whatever the case might be we are not interested in that as we have to only calculate the kinetic energy in which the sign makes no diffrence

    Kinetic Energy Paradox: What Went Wrong?

    the train is going in opposite direction of the car or accorgdng to paul the car is moving backwards...while calculating the relative speed you havnt taken the sign of velocties...if you rightfully consider the signs then it will be -100-100=-2009according to paul the car is moving backwards...

    How Does Reference Frame Affect Kinetic Energy Calculations?

    its kinetic energy is 0 in the first case and 16 in second...and the body will do work according to the kinetic energy in the frame of reference only .so in the first case no work will be done

    Kinetic Energy Paradox: What Went Wrong?

    are trying to say that if paul knows that in the second section the car takes 3x amount of fuel against 5/3 as calculated by him then he can logically conclude that he is a part of bigger system and is not looking at the whole thing

    Kinetic Energy Paradox: What Went Wrong?

    if the rails are frictionless then there would be no requirement of force to maintain speed of 100

    Kinetic Energy Paradox: What Went Wrong?

    from pauls point of veiw the accelerates from -100 to -200 because he is moving in opposite direction of the car

    How Does Reference Frame Affect Kinetic Energy Calculations?

    but how will know about the bigger frame of refrence that is u r considering Earth as a part of it

    Kinetic Energy Paradox: What Went Wrong?

    m not discusing the exact question...i want to discuss the spirit of it
  15. P

    Kinetic Energy Paradox: What Went Wrong?

    the fuel required for 0 to 100 in peters frame is same as the fuel required 100 to 200 in pauls frame...and if u are trying to sat that paul is making mistake by adding trains velocity then how how can conclude that he is making a mistake...becuase he can never know whether he is moving or the...
