# NATURAL FREQUENCY OF A VIBRATING SPRING

Spring Natural Frequency Calculator to calculate natural frequency of a vibrating spring with a weight at lower end. Spring is fixed from upper end and the lower end is free. Natural frequency of spring mass system formula is $${ f }_{ 1 }=\frac { 1 }{ 2\pi } \sqrt { \frac { k }{ M } }$$.

Here k is spring constant and M is mass.
