Tension Force

Tension force is the force exerted by a rope or a cable. For example, if an object is pulled by a rope/cable with 8N, then the force near the object end of the rope/cable is also 8N in the opposite direction (assumming that the rope/cable is massless). If the rope/cable has mass, then some of the 8N force will be used to accelerate the rope/cable, and thus the other end of the rope/cable would exert a lesser force in the opposite direction.
