This study aimed to investigate student reasoning about harmonic oscillations. We conducted a semi-structured interview based on three situations of harmonic motions-(1) a mass attaching to spring and horizontally oscillating without damping, (2) same situation but vertically oscillating and (3) a mass attaching to spring and oscillating in viscous liquid. Sixty one second-year students taking a vibrations and wave course at Chiang Mai University, Thailand participated in a fifteen-minute

As results, we found that most students had misconceptions about angular frequency and energy mostly in the second and third situations.
