Homework Help: The dimensions of force

  1. Feb 23, 2014 #1
    I'm doing practice problems:
    I am confronted to this:
    The dimensions of force are (x means “multiplied by”):
    (a) kg.m.s-2,
    (b) mass x length x (time)-2,
    (c) Newtons,
    (d) mass x acceleration.

    I need someone to back up my reasoning.

    It says dimensions, so I'm going towards (b) because (a) and (c) are units and, as for (d), acceleration is not a dimension.

    That would be my answer too, for the same reasons you mentioned.
