Here's a breakdown of why:

* Action exerted on a body: This refers to an interaction between an object and its surroundings.

* Change the state of rest or motion: Force can cause an object to start moving, stop moving, or change its direction of motion.

* Magnitude and direction: Force has both a strength (magnitude) and a specific direction in which it acts.

In simpler terms: A force is a push or pull that can make things move, stop moving, or change the way they are moving.
