Your photographs must have a sense of movement.
Photo #1 - Blur: The subject (person) moving/blur. This is done by having the camera on a tripod and using a slow shutter speed. Try 1/30, 1/15, 1/10, 1/8, 1/4, or 1/2.
Photo #2 - Pan: The second image must be of the subject in focus and not blurred but the background blurred. This is done by panning the camera on a moving person. Try 1/30, 1/15, 1/10, or 1/8.
Photo #3 - Frozen: The third image is of frozen movement. This is done with a very fast shutter speed. 1/500 or faster is best. You will need a lot of light. This photo would work best taken outside. Your subject should be moving fast - running, jumping, twlrling, kicking, catching, etc.
