Here's a breakdown:

* Tension is a force that exists within a rope, cable, chain, or similar object when it is pulled taut. It acts in the direction of the pull and is often described as the "pulling force."

* Think of a rope tied to a heavy object. When you pull on the rope, the rope stretches and experiences tension. The tension force within the rope is what ultimately pulls the object.

Here are some other related terms:

* Tensile strength: This refers to the maximum amount of tension a material can withstand before it breaks.

* Stress: This is the force per unit area within an object. Tension is a type of stress, specifically a pulling stress.
