I'm have such a hard time with tension

AI Thread Summary
Tension is a physical concept that describes the force transmitted through a medium, such as a string or rope, which remains consistent throughout its length. It is not merely the net force but involves the interaction between multiple objects and their intermediaries. The definition of tension encompasses various scenarios, including internal tension in springs, highlighting that it is not a singular force but a relationship between components. The effectiveness of force transfer in a system is influenced by its design. Understanding tension is crucial for analyzing physical systems and their dynamics.

I'm have such a hard time with "tension"

I know a few things about tension, but it never really came through to me.

i know that "tension is the same in every part of one string, and pulleys just change the direction of the force."

At first i thought tension was just the net force, but i guess not! Can someone please explain tension super-thoroughly? Thanks!

My definition: Tension is a physical concept between two or more physical objects(or object aspects) utilizing one or more physical intermediaries to transfer application of force.
Even the internal tension of a compressed spring, for example, is characterized by the relationship between spring "segments" So, tension is never unitary.
In short, tension sets-up a transfer of force in a physical system. To what degree the force is actually transferred is dependent on system design.
 

Thread 'Is calling fictitious forces "not real" just about terminology?'

Hi there, im studying nanoscience at the university in Basel. Today I looked at the topic of intertial and non-inertial reference frames and the existence of fictitious forces. I understand that you call forces real in physics if they appear in interplay. Meaning that a force is real when there is the "actio" partner to the "reactio" partner. If this condition is not satisfied the force is not real. I also understand that if you specifically look at non-inertial reference frames you can...

Thread 'Derivation of Hamilton's Principle: Questions'

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...
