The SI unit of force is the newton (N). One newton is defined as the force required to accelerate a mass of one kilogram at a rate of one meter per second squared. In terms of SI base units, it is expressed as 1 N=1 kg⋅m/s21,\text{N}=1,\text{kg}\cdot \text{m/s}^21N=1kg⋅m/s2
. The unit is named after Sir Isaac Newton in recognition of his work on classical mechanics, particularly Newton's second law of motion, which states that force equals mass times acceleration (F=maF=maF=ma)
