| - | When we attach a second 100N/m spring to the end of the first and then attach the mass, both springs will stretch 1m. That is, the overall stretch of the spring-mass system is 2m. //In series, each spring stretches as if the mass were attached to just that spring//, and the sum of all those stretches gives the overall stretch. | + | When we attach a second 100N/m spring to the end of the first and then attach the mass, both springs will stretch 1m.
