Difference between dolly and trucking shot and zoom

The zoom is supposed to bring that image towards you. That can make the audience feel like something may happen to the character. A dolly towards the character in the same scene can make the audience feel like the character may feel or just to show how the character is feeling. Trucking while the character is moving can help the audience see the character going from A to B and to see how the character may feel while they are going from A to B.
