this is another conceptual question, so sorry for not following the template. I thought that angular frequency and angular velocity shouldn't be the same thing, but after going through some of the forum threads, there was the idea: "the only difference between angular frequency and angular velocity is ---the former is a scalar and the latter is a vector. They have the same magnitudes. " which got me quite confused, because in general simple harmonic motion, angular frequency is constant and angular velocity is a varible...as in a pendulum or other motions. so i was wondering if someone could enlighten me on the matter? Thank you.
