Uncertainty particle function evolves over time

  1. Apr 10, 2008 #1
    1. The problem statement, all variables and given/known data

    The position of a proton is measured with an accuracy of [tex]\Delta[/tex]x = 10^-11 m
    Calculate [tex]\Delta[/tex]x one second later. Assume v << c.

    2. Relevant equations

    Heisenbergs uncertainty principle perhaps.

    3. The attempt at a solution

    I assume this requires knowledge about how the particle function evolves over time, but because the function is unknown in this case, its random how it evolves...

    Thought a bit more about it. If i calculate the uncertainty in momentum by using heisenbergs uncertainty principle. Then multiply it by t and divide by m, to calculate [tex]\Delta[/tex]x a second after. Does this sound right?

    Add that answer to Delta x.
