According to the Merriam Webster dictionary:
Moment - a very short period of time
Does the word "moment" in quantities like the moment of force or moment of inertia refer to this colloquial meaning of "moment" too? If so, where exactly is the "short period of time" involved in, say, moment of force? For me it has always been just the tendency of a force to rotate an object around an axis and I don't see any reference to time there.
