* Massless: A massless rope has no weight. Weight is the force of gravity acting on an object's mass. Since the rope has no mass, it experiences no gravitational force.
* Tension: A rope, even a massless one, can transmit tension. Tension is the force exerted along the rope's length, pulling on objects attached to it. This tension can be upwards, downwards, or even sideways, depending on how the rope is being used.
Example:
Imagine a weight hanging from a massless rope. The weight pulls downwards on the rope, creating tension. The rope then transmits this tension upwards to the point where it's attached, balancing the weight's force.
Important Note: While the rope itself doesn't exert a downward force, it *transmits* the downward force of any object attached to it.
