Z plane in vectors

  1. Jun 17, 2008 #1
    How would one draw a vector traveling in the positive z direction? Would it be a line comming out at you?

    So this is just a very basic question but I do not know how to do it so can someone just give me a quick answer if you can or point me in the right direction because my book only discusses th x and y plane.

    In my physics class we used a circle with a dot inside for a vector in the positive z direction, and a circle with an x in it for the negative z direction. Unless your teacher has a preference, you should feel free to make up your own notation! Don't let the notation Nazi's oppress you! LOL

    A dot? How would you do the components of a dot?

    A force vector that has a non-zero z-component would have to be split up so that the z-component is drawn separately. Granted, this is an undesirable situation that is best avoided where possible.

    I can't avoid it so how would i split it up and draw it seperately

    This website explains vector components quite well:
