I am just learining basic dynamics from spring mass system.(adsbygoogle = window.adsbygoogle || []).push({});

there is a horizontal spring fixed to the wall and a mass is at the end.

When the mass is displaced by a force F to the right the spring stretches to a distance X. Now i draw the STATIC FBD. The

eqn is f-kx=net force on the mass. Now i draw the kinetic diagram and the equation i derive is

f-kx=ma where a is the acceleration of the mass m. So for this spring mass system the dynamic equation is

f-kx-ma=0.

Is what i have done is true and correct?
