A push or pull one body exerts on another body is called a force.

Here's why:

* Force is a fundamental concept in physics that describes an interaction that can cause a change in an object's motion (acceleration) or its shape (deformation).

* Pushing and pulling are common examples of applying a force.

* Forces can be contact forces (like pushing a door or pulling a rope) or non-contact forces (like gravity pulling you towards the Earth).
