Conservation of mechanical energy formula. What is x ?

AI Thread Summary
The discussion centers on the conservation of mechanical energy formula, specifically clarifying the variable "x." It is identified as the amount a spring is stretched or compressed, while "k" represents the spring constant. Participants express appreciation for the clarification, noting the challenges of working with formulas lacking proper descriptions. The conversation highlights the importance of understanding these variables for completing related exercises. Clear definitions enhance comprehension and facilitate problem-solving in physics.

x is the amount by which a spring is either stretched or compressed, and k is the spring constant of the spring.
 


Ah, now I can go back finishing that damn exercise I was working on. When you're handed formulas without proper description of them, it's not very conducive. Thanks mentor! :)
 


You're welcome, contributor I:#$-)
 
I have recently been really interested in the derivation of Hamiltons Principle. On my research I found that with the term ##m \cdot \frac{d}{dt} (\frac{dr}{dt} \cdot \delta r) = 0## (1) one may derivate ##\delta \int (T - V) dt = 0## (2). The derivation itself I understood quiet good, but what I don't understand is where the equation (1) came from, because in my research it was just given and not derived from anywhere. Does anybody know where (1) comes from or why from it the...
