Question:
please explain this in written format as an example so that a 14 year old may understand it please. N = kg m/s^2

Replies:
We make measurements of many different things. For example, the label we put on time measurements is seconds. When we measure mass, we use the label kilograms. Force is measured in units of Newtons, abbreviated N.

Sir Isaac Newton investigated forces and found that there is a relationship among force, mass and acceleration. If we increase the force on an object (mass), its acceleration increases. If we increase the mass of an object, its acceleration decreases. In a simplified form, the relationship is F=ma (force = mass * acceleration). We measure mass in kg, and acceleration in m/s/s (m/s^2). Looking at the units of this relationship, we get: N - kg m/s^2
