Here's why:

* Newton's Second Law of Motion: This law states that force (F) is equal to mass (m) multiplied by acceleration (a): F = m * a.

* Derived Unit: The Newton is a derived unit, meaning it's defined based on other fundamental units.

* Mass is measured in kilograms (kg).

* Acceleration is measured in meters per second squared (m/s²).

* Therefore: 1 Newton is equal to 1 kilogram * meter per second squared (1 N = 1 kg * m/s²).
