Non-Native English Speaker: Torpidity Coefficient

[Good old Grim]

I am a non-native English speaker, but i have to write my homework in English due to IB programme.

Anyway the question is - what is the correct term for torpidity coefficient (direct translation from Latvian). It is the force required to stretch smth (a wire, a spring or smth similar) to extend it 1m longer. And is measured as follows [k]=N/m

That can take on a few terms in our language. F=kx is the basic spring definition and k is the "spring constant." It can also be referred to as Hooke's Law (ref http://hyperphysics.phy-astr.gsu.edu/hbase/permot2.html#c3).

 

[quicknote]

The correct term for "torpidity coefficient" in English would be "stiffness coefficient" or "spring constant." This term refers to the measure of how resistant a material is to being stretched or compressed. In your example, the stiffness coefficient would be measured in units of N/m, which stands for newtons per meter. This is the standard unit for measuring force and distance in the metric system. I hope this helps clarify the term for you. Good luck with your homework!
