Radans physics homework

  1. Feb 5, 2014 #1
    Which equation is valid only when the angular measure is expressed in radians?
    α = Δω/Δt

    ω= ΔΘ

    ω^2 = ωø^2 + 2αθ

    ω = Vt/r

    I don't know where to start in this question.

    Start by writing down what the different symbols mean in the equations. Unless you know that, the whole question is meaningless. (I can guess what some of the symbols stand for, but not all of them).

    Then, think if the equations would make any sense if the angles were in degrees and not radians.
