Yes, you would hear a change in pitch as you move towards or away from the source of the sound. This is due to the Doppler effect, where the frequency of the sound waves changes as the distance between the source and the observer changes.
This is known as the Doppler effect. As the train approaches you, the wavelength of the sound waves it emits are compressed, and therefore the whistle sounds higher. When the train is moving away, the wavelengths are extended, causing the whistle to sound lower. If the train were not moving at all, the pitch you would hear from the whistle would be somewhere between the high and low pitches you hear when the train is moving.
The raising and lowering of the whistle's pitch due to the alteration in the relative speed of the whistle as it goes by you, described by two terms that can be discovered by reading your homework assignment.

The change in frequency of sound waves in the Doppler effect is heard as a change in pitch. If the source and observer are moving towards each other, the pitch is perceived to be higher, and if they are moving away from each other, the pitch is perceived to be lower.

Yes, you would hear a change in pitch. As the train approaches you, the pitch of the whistle would sound higher because the sound waves are compressed. As the train moves away from you, the pitch would sound lower as the sound waves are stretched out. This is known as the Doppler effect.

A whistle is a High Pitch because its really loud and not really low.

The referee blows his whistle and points back up the pitch to the halfway line. Indicating the match shall be restarted from the spot.
the pitch doesnt actually change but it might sound quieter to you because the sound it being blown away

The ball is there to make the whistle tone more noticeable. It does so by moving around, raising and lowering the pitch and volume as it moves. The result is much more attention-grabbing than the flat tone that would come from a ball-less whistle.
