This is a bit of a tricky question because forces are always pushing or pulling, but they can be both attractive and repulsive. Here's a breakdown:

* Electromagnetism: This force can be both attractive (like magnets pulling together) and repulsive (like magnets pushing apart).

* Strong Nuclear Force: This force is responsible for holding the nucleus of an atom together. It is extremely strong at very short distances, but quickly falls off with distance.

Important note: These forces are always pushing or pulling. The distinction is whether they cause things to come closer together (attractive) or move apart (repulsive).
