ahh, then never mind.
I will just remove the question, thanks anyway.
 
Thread 'Why wasn’t gravity included in the potential energy for this problem?'
I’m looking at the attached vibration problem. The solution in the manual includes the spring potential energy but does NOT include the gravitational potential energy of the hanging mass. Can someone explain why gravitational potential energy is not included when deriving the equation of motion? I tried asking ChatGPT but kept going in circles and couldn't figure out. Thanks!
