The SI unit of force, the Newton (N), is defined based on Newton’s second law of motion, which states that force (F) equals mass (m) multiplied by acceleration (a): F = ma. The SI unit of mass is the kilogram (kg), and the SI unit of acceleration is meters per second squared (m/s²). Therefore, 1 Newton is defined as the force required to accelerate a mass of 1 kilogram at a rate of 1 meter per second squared. This gives the relationship 1 N = 1 kg * (m/s²), or 1 N = 1 kgm/s².
