    firstly subtract all the speed with avrage speed and take their modulus( consider their magnitude only)

    actually it is the difference of the speed from average speed....

    now u take the differences in each case and take their average...

    what is the formula for finding the uncertainty

  37. anonymous

    so u get all those values that are the differences from mean that ar 0.2, 0.1, 0.4 , 0.1 , 0.0..... so take average difference...

    ( 0.2+ 0.1+ 0.4 +0.1 + 0.0 ) /5 = 0.8/5

  39. anonymous

    thus formula for uncertainity is \[v _{av}- \Delta v _{av}\]
