Here's why:

* Newtons (N) are the units of force. Force is a push or pull that can cause a change in an object's motion.

* Acceleration is the rate of change of velocity. It is measured in meters per second squared (m/s²).

The relationship between force, mass, and acceleration is described by Newton's Second Law of Motion:

Force (F) = Mass (m) x Acceleration (a)

So, if you know the force and the mass of an object, you can calculate its acceleration.
