^Just to add to that, Weiss has been shown to use her Glyphs to make platforms that are able to repel or attract things. During her fight against the Boarbatusk, she jumps onto a platform before launching herself at the Grimm and killing it.

However when Ruby attacks the Beowolf in the Emerald Forest, she seems to materialize in front of the Grimm before attacking it. She also moves fast enough to make Weiss question how she did that. To me, this could mean that Weiss isn't aware that everyone has a Semblance and believes her Glyphs come from using Dust; making her question how Ruby moves fast without Glyphs. However this obviously proves that Ruby's Semblance allows her to move father than Weiss' Glyphs. Ruby's Semblance probably also allows her to move in various directions instead of Weiss' Glyphs, which launch her in one direction at a time.
