* Compression force pushes an object together, reducing its volume.

* Tension force pulls an object apart, stretching it.

Here's a simple analogy:

* Imagine a spring. When you push on it, you're applying a compression force. When you pull on it, you're applying a tension force.

Other terms that are sometimes used to describe the opposite of compression force include:

* Tensile force

* Traction force

* Stretching force

However, tension force is the most common and accurate term.
