According to dictionaries, one of the meanings of the word dynamic is:
a system with continuous change
However, it's used as adjective. I'm writing a text in which I need to refer to continuous change and changeability and I thought of the word dynamism. In other words, I need the noun form of the dynamic. However, seems that dynamism is not used as that meaning.
For example, instead of the level of changeability and the amount of change in a system, I'd like to write system's dynamism level.
Can I use dynamism in that meaning? If not, what word should I use?
