This first image physically shows motion - the viewer understands that the girl is blowing the pieces of confetti, and that they are being scattered everywhere. The motion makes the image feel dynamic and exciting, and since the girl is blowing right at the camera, that adds a lot of interest too! The viewer feels close and if the confetti is flying out toward you. This motion caught in a moment implies a broader context of time - a story of what this girl is doing starts being told, and the viewer can imagine what happens before and after this moment.
This image clearly involves actual events and is one snapshot of time. The man is tearing up, supposedly because this is the first time he sees his bride on their wedding day. His hand being up toward his face - not at his side or perfectly posed - shows that more is going on; there is a sense of dynamism and action. It pulls the viewer into the story. We know what is happening because of the hand captured in motion.
Here is another example, one that I took. Again, this image conveys the idea of time, movement, and motion. The ripples around the duck and on the lake in general really give the feeling of motion and add interest to the piece. The duck is going away from the image, as well, which is interesting. It has a different feel than if the duck was coming toward us - that would probably pull the viewer in more and make them feel welcome. However, the duck is moving toward the large reflection which points down, so the image still seems to work. The duck is swimming toward the center of the frame and has space in the image to move still, which helps the viewer out and makes it feel more natural.
