Implied motion is mostly prevalent in the curves. The negative space and contrasting colors draw the viewers eyes to the girl's silhouette, then to the teapot. Turning our attention to the teapot's curves directs the eye downwards and into the waves that wrap around. Viewing the teapot tipped over we have an expectation of liquid falling from the teapot adding to the suggestion of movement.
These posters are examples of implied movement. The repetition of shapes in a diagonal manner gives a sense of direction. There are also the crossing of patterns, producing static and energy. Followed by the diminishing size of shapes to further the claim of movement. Negative space acts as a backdrop to the motion of the objects.
