Ropes are often treated as massless
In this case, there is only one tension associated
It is better to label tension as
“Force of rope on X” rather than just “tension”
in order to clarify the role of tension in a given problem
If a rope is massive, the tension
can change depending on where
Can you see why? (draw a force diagram)
