The type of force that pulls in two opposite directions is called a tension force.

Here's why:

* Tension refers to the pulling force that exists within a stretched object, like a rope or cable.

* This force acts equally and oppositely on both ends of the object.

Example:

Imagine a tug-of-war. The rope is under tension because the two teams are pulling on it in opposite directions. The force of tension is what keeps the rope taut and allows the game to be played.
