Forces with constant velocities

  1. Jul 21, 2014 #1
    I was wondering why can't I use formulas from the "Special Relativity" in cases like:
    F=mv^2/r Or F=qv•B
    I understeand that in the F=mv^2/r the velicity isn't constat,it changes with the vector,are there any other formulas?

    Special relativity relates observations between inertial reference frames.
    The presence of an unbalanced force indicates a non-inertial reference frame.
    Another, famous, example is gravitation.

    There are techniques for handling accelerations in special relativity - you'll get to those later.
