What are the units for a Newton (N)?

A Newton (N) is the unit of force in the International System of Units (SI). It is defined based on Newton's second law of motion, which states that force is equal to mass times acceleration (F = m * a).

In this context, mass (m) is measured in kilograms (kg) and acceleration (a) is measured in meters per second squared (m/s²). Therefore, when you multiply mass by acceleration, you get:

Force (in Newtons) = mass (in kg) * acceleration (in m/s²)

This results in the correct units for a Newton being kg * m / s², representing the force required to accelerate a one-kilogram mass by one meter per second squared.

Understanding this relationship is crucial in fields such as engineering and physics, where the calculations of force are common. The other units provided do not represent force accurately in the context of the defined parameters of mass and acceleration.
