The essential goal of this investigation was to break down the free oscillatory motion of dynamic systems and the powers related with the motion. This is the investigation of a free vibration of two states of a spring mass system that is un-damped and damped. Free vibration happens when a mechanical system is set in motion with an underlying info and permitted to vibrate unreservedly. Cases of this kind of vibration are pulling a kid back on a swing and lifting up or hitting a tuning fork and giving it a chance to ring. The mechanical system vibrates at least one of its regular frequencies and damps down to motionlessness. A definitive objective in the investigation of vibration is to decide its impact on the execution and security of the system concerned. Subsequently the investigation of oscillatory motions is an imperative advance towards this objective. The investigation demonstrates that damping proportion (ζ) is directly proportional to current. The lighter the current, the lighter the damping ratio, and the more grounded the damping power.
