If you divide a force measured in newtons (1 newton = 1 kg*m/s^2) by a speed expressed in meters per second, in what units will the answer be expressed?

In SI units,

1 N force = 1 (kg-m) / s²

Speed has units of m/s.

If 1 N is divided y 1 m/s, the resultant units will be

(1 (kg-m) / s²) / (1 m/s)

= 1 kg/s

Answer: the units will be kg/s

Note:

The above units are correct but they do not provide the measure of a physical object.

Nevertheless, it is necessary to keep track of units, because they eventually reveal the units of a physical object when a computational procedure is completed.
