## Question:

A mass {eq}m {/eq} on the end of a spring oscillates with angular frequency {eq}(\omega) {/eq}. The mass is removed, the spring is cut in two, and the mass is reattached. What is the new angular frequency?

## Spring Constant of Springs Connected in Series and Parallel

Spring constant or the force constant of the spring can be defined as the force required to elongate or compress a spring by unit length. If a spring is stretched by *x* distance by applying a force *F*, its spring constant can be expressed as {eq}k = \dfrac { F } { x }
{/eq}. Spring constant is expressed in *Newtons per meter*.

- When
*n*springs of spring constants {eq}k_1, \ \ k_2, \ \ k_3, \ \ ...... \ k_n {/eq} are connected in series, the inverse of the effective spring constant of the series combination can be expressed as {eq}\dfrac {1 } { k_s } = \dfrac{1 } { k_1 } + \dfrac { 1 } { k_2 } + \ ..... \ \dfrac { 1 } { k_n } {/eq}

- When
*n*springs of spring constants {eq}k_1, \ \ k_2, \ \ k_3, \ \ ...... \ k_n {/eq} are connected in parallel, the effective spring constant of the parallel combination can be expressed as {eq}k_p = k_1 + k_2 + \ ...... \ k_n {/eq}
