Ruby's semblence is not speed, but actually velocity. As in she does not apply physical force, but manipulates the velocity the object is already moving. It explains how she can zoom so suddenly without suffering from concussions or an aneurysm just from the acceleration/decelleration forces on her body. Or swinging that massive scythe around like it weighs nothing. She does not know this due to Qrow's personal tutoring, deliberately misinforming his niece to protect both her and everyone around her from an accident (Uncle Qrow! Daddy tucked me into bed and his arms flew off!)
