    Displacement is the difference between where you end up and where you start.

    If you go around the field exactly twice, how far are you from where you started?

    Yes, I know that :) But what was the first and last point you went to?

    Think about it (and draw a diagram!)

    Physics takes some imagination. You should always help your imagination out by drawing a picture, but this one is easier than you think. (here's a hint: the perimeter of the field is irrelevant)

    Did he return to the same point?

    Yep. If you got exactly twice around something that's the same as going exactly once around - you'll end up in the exact same place you started from.

    And that's the same as not going anywhere at all!

    Two primary tools for physics: math skills and common sense!

    Math skills= Calculator!! And common sense= I think I need to work on that a bit.

    If you go exactly twice round a field of perimeter 340m, what is the distance you travel?

    You know the distinction between distance and displacement?

    Then imagine if you did twice that perimeter in a straight line, how far did you go?
