Example Question #1 : Interpreting Harmonic Motion Diagrams
A block of mass is attached to two springs, each of whose spring constant is . The ends of the springs are fixed, and the block is free to move back and forth. It is released from rest at an initial amplitude, and its period is measured to be . What would the period be if the spring on the right side were to be moved to the other side, attached along side of the other spring?
Because the springs are effectively in a parallel arrangement already, moving one does not change the effective spring constant, and therefore does not affect the period.
