[[Oscillations]]


# Summary
* Period is how long it takes in seconds, frequency is how many times in a second.
* $T=1/f$
* Mass spring oscillator has period $T=2\pi\sqrt{m/k}$
* Small angle pendulum has period $T=2\pi\sqrt{l/g}$
* Pendulum formula only works on small angles (~15$\degree$), larger angles increase period.
