How does the extension of two or more springs in series or parallel compare with the extension of one spring?
My aim is to find out the extension of a single spring compared with springs in series.
I think that the springs in series will extend more than one spring. I think that the springs in series will extend twice as much as one spring. If the extension is x, therefore the load of one Newton on two springs would be 2x as the load of one Newton is on each spring and not shared.
One spring is x, two springs in series give 2x as each spring feels the one Newton mass. The parallel share the mass with each feeling 0.5. Parallel is x/2 compared to one spring, x and nx in the series.
I will keep this a fair test by keeping the length of each spring the same. I will measure in the same units and keep the same conditions for each experiment.
Hooke’s Law supports my prediction:
