Work done

  1. Nov 8, 2006 #1
    the question is what is the work done by F on the ball
    so this is what i did
    since F is constant we can apply
    and now here's my question, does the work done in this case depends on the path (curve) or the displacement (straight line)?

    so i'm trying to find the work done by F on the ball

    and this is what i got
    sqrt(2LH) is the displacement from the bottom to the position with height H.

    So, i'm just wondering if this is correct or i'm missing something

    It depends on the component of the displacement in the direction of the force. (Read up on the meaning of the scalar/dot product of two vectors.)
