Unformatted text preview: not (do) change in time. if Example: Mx’’(t)=f(t) & M(t)x’’(t)=f(t) Example: For time-invariant systems: For 1st law: A particle remains at rest or continues to move in a particle straight line with a constant velocity if there is no unbalancing force acting on it. 2nd law: : translational translational Time shift Time shift Sys : rotational rotational 3rd law: For every action has an equal and opposite reaction For This course deals with time-invariant systems.
