Tension

 Tension is a type of contact force which exists in a string, rope, wire, or cable when it is being pulled, specifically on both of its ends. In opposition to being pulled, the string applies an equal tension force on the objects, pulling them towards itself.
Tension is a vector, and therefore has a direction and a magnitude.
The force itself is called a tension force because the rope is in a state of tension.
