F=-kx when talking about a mass at the end of a horizontal spring(adsbygoogle = window.adsbygoogle || []).push({});

therefore ma=-kx

rearranging we get a= -(k/m)x

then it says if we define ω^{2}=k/m we then have a generic form :

a= -ω^{2}x

My question is what does "if we define ω^{2}=k/m" mean? where does this come from?is it just any random assumption?
