Alright tension has always got me confused... and takes up a lot of time because I have to think pretty hard about them. Anyway here's my question (s) Say you have a hanging object, and connecting the object to the ceiling is a massless string. Will the tension near the object be the same as the tension near the ceiling? Say I have two objects connected by a massless string, I hold object 1 and pull on it upwards with object 2 hanging from object 1 (using the massless string), will the tension force at object 1 be different from the tension force at object 2? Will the tension across the string ever be different for any case (like at both sides of a string)? And my book says that the the force is not labelled a tension if the string's mass is included, I don't understand what it means? These are a lot of questions but it would help a lot with my understanding :) THANKS!
