This means that the net force on any section of a rope when extended is considered to be zero independent of the acceleration of the rope ($\Sigma\vec{F}=m\vec{a}$ with $m=0$), allowing a perfect transmission of force from one end of the rope to another. The force transmitted from one end of the rope to the other is the **tension** in the rope, and it should be noted that all real ropes have a maximum tension above which they break.
