What does one Newton equate to in measurement terms?

One Newton is defined as the force required to accelerate a mass of one kilogram at the rate of one meter per second squared. This relationship is articulated through Newton's second law of motion, which states that force equals mass multiplied by acceleration (F = m × a).

In simple terms, if you apply a force of one Newton on a one-kilogram object, it will accelerate at one meter per second squared. Therefore, the correct measurement for one Newton integrates mass (in kilograms) and acceleration (in meters per second squared), resulting in the unit represented as kilograms times meters per second squared (kg*m/s^2). This highlights the fundamental relationship within classical mechanics, making option B the accurate representation of one Newton.

The other options do not accurately capture this foundational concept. For instance, measuring Newtons in terms of kgm/s or kgm^2/s^2 would either describe different physical quantities or distort the relationship of force to mass and acceleration, while m/s^2 alone denotes acceleration, lacking the context of mass essential to the definition of force.
