What's the difference between 18mm focal length and 55mm focal length when shooting the same scene?

With the same shooting parameters and shooting distance, the main differences of shooting the same scene are: 18mm lens shoots a wider picture, contains more scenes, and has smaller objects; 55mm lens shoots a narrower picture, and the objects in the picture are slightly larger than 18mm lens.
