It first talks about harmonic motion, which is the basis for all vibration...
If m is the mass attached to the spring (with spring constant k) , {eq}\Delta {/eq} is the static deflection, and x is the deformation given to the spring-mass system, then natural frequency is expressed as: (Neglecting mass of the spring) {eq}\displaystyle f_{n...
(i) Determine the natural frequency of the spring-mass system in both rad/s and cycles/s (Hz)(ii) Determine the placement x of the mass as a function of time if the 20kg mass is released from rest at time t=0 from a...
Here, k is the spring constant for the spring in question and m is the mass of the ball. The spring constant is measured in Newtons/meter. Springs with higher constants are stiffer and take more force to extend. To calculate the natural frequency using the equation above, f...

Here, k is the spring constant, which is determined by the stiffness of the spring. Higher spring constants correspond to stiffer springs. m is the mass of the ball. Looking at the equation, we see that: A lighter mass or a stiffer spring increases natural frequency. ...
