The focal length tell us what Angle of view and how close to the camera you subject appears. some call it how much zoomed in you are.

Focal length is often referred to as when using a 35mm film/sensor. By changing the focal length you change the Angle of view but not the Perspective distortion, the Perspective distortion change because you tend to move relative to your subject then changing focal length.
