Question

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?

Answer 1

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.
