Problem

One newton is numerically equal to the force that produces an acceleration of 1 m/s² in a mass of 1 kg. Which of the following combinations of fundamental units represents one newton? a) kg m/skg\,m/s b) g cm/s2g\,cm/s^{2} c) kg m/s2kg\,m/s^{2} d) kg m2/s2kg\,m^{2}/s^{2}
Intuitive explanation

The newton is defined through Newton's second law: F=maF = ma. To find what units make up a newton, substitute the fundamental units for mass (kg) and acceleration (m/s²) directly into this equation—acceleration itself breaks down into meters per second squared. This shows you exactly which base units combine to create the unit of force.
