Does time period of SHM vary with frame(inertial and non inertial)??

1. The problem statement, all variables and given/known data

There is an SHM. First observer is watching it from inertial frame of refrence and secodn is from non inertial will there any change of time period for both observer.

2. Relevant equations

just think about it.

3. The attempt at a solution

I have done a question on SHM. that was solved example first i do that with my self with non inertial frame of reference and then when i see it in book it was done by inertial frame. However my answer was matching with answer of the book.

After i think on it. I come to conclusion that speed is not too fast so clock of both observer run with same speed hence both observers will see it with same time period..
thanks..
waiting for your response.

So... we're assuming non-relativistic speeds, and the question is whether two observers (one being accelerated) will see the same frequency for the SHM oscillator? One important thing is whether the acceleration of the observer is constant with time or not.

consider both the cases.then??

hmm. For a physical object oscillating in space, you need to say what you mean by the period of oscillation, because from the point of view of the accelerated observer, the oscillator might never repeat its motion.

For some more abstract oscillator like an electrical circuit, it is more simple. In this case, I think you were right that:

Also depends on what "watching" means precisely. "Observing" sound waves might not be the same as "watching" a pendulum.
