The correct response is: Pete is not correct because friction will cause the spring to fall and rise with a shorter distance during each oscillation. The spring will eventually come to rest entirely.
Reasoning: In a real-world scenario, oscillations will eventually be damped due to friction and air resistance. These forces convert mechanical energy into thermal energy, causing the amplitude of the oscillations to decrease over time. Eventually, the system will come to rest, and the motion will not continue indefinitely.
