To start the investigation on the mass–spring–damper presume the damping is negligible and that there is no external force applied to the mass (i.e. totally free vibration). The pressure placed on the mass through the spring is proportional to the amount the spring is stretched "x" (assuming the spring is https://lukasgaunf.blogocial.com/details-fiction-and-isolator-vibration-damper-64685288
