Newton (unit)
Definition
The Newton (N) is the unit used to measure force in the International System of Units (SI). One Newton is equal to one kilogram-meter per second squared (kg·m/s²).
Analogy
Imagine you have a box that weighs 1 Newton. If you push it with 1 Newton of force, it will start moving at a constant speed. But if you push it with 2 Newtons, it will accelerate and move faster.
