It isn't. Different units are used for force. However, the international unit for force is the newton.
Newton (N)
The SI unit for force is the Newton.
The gravitational force is always attractive.
The unit of force is the newton, no matter what type of force. The unit for the "force" that pushes electrons or other charged particles is the volt - but it's not really a force.
Reduced-force
Sodium chloride "formula units" form a very large lattice.

What type of unit did you had in mind? Manoeuver elements are always going to be mobile, naturally, are are logistics and other units directly supporting them. Some units don't necessarily need to be mobile, however.
No, not always. It depends on the type of data you collect. If it is quantitative data, you will be able to calculate a mean. If it is qualitative data, a mean can't be calculated but you can describe the data in terms of a mode.
For just about any type of unit, different units are used between the English system and the SI (metric) system. In both systems, there are units for length, area, volume, mass, force, temperature, etc.
A police officer is always using force. A police officer simply being present at a location is a type of force, as it changes how people act and display themselves.
Calculated risk means that the beginner knows the consequences. This is not true. Risk of this type is always unnecessary, but they don't take that as a risk. It's only an adventure. "I am not feeling anything bad for now, why would it be a risk?"
Not knowing what units you are using (is that newtons per meter? pounds per inch? gram-force per micron?), and what type of spring you are talking about, little can be said about that.
