Extending on the Barrier part, we know that a single element can appear in different forms when it comes to Dust. For example, Water, Ice and Steam. In the end, they are all the same element, in different forms: Liquid, Solid and Gas.

I once made a post where I analyzed the apparent naming conventions of Dust and their types.

Long story short, I reached this conclusion: Gravity is Kinetic, in the form of a Kinetic blast that pushes. While Barrier is also Kinetic, but in the form of a counter-force. Instead of pushing, it stops.
