What is the total distance traveled by the mass after a time interval T ? In the time interval time interval T (the period), the mass goes through one complete oscillation complete oscillation back to the starting point. The distance it covers is: The distance it covers is: A + A + A + A A + A + A + A (4 (4 A ). ). A mass on a spring in SHM has amplitude A and period T .

What is the net displacement of the mass after a time interval T ? 1) 2) A /2 3) A 4) 2 A 5) 4 A The displacement is x = x 2 x 1 . Since the initial and final positions of the mass are the same (it ends up back at its original position), then the displacement is zero.
