I'm trying to understand the following question:
The force generated by a spring of spring constant $k$ is $F = -kx$, where $x$ is the displacement from equilibrium. A cube of mass $m$ and length $L$ is attached to the spring, and oscillates around the equilibrium point.
I'm trying to determine which variables effect the frequency. From what I found it is dependent on $k$ and $m$ only. Why is that? I expected it to be effected from $x$. Any insight will be highly appreciated.
