Answer 1

When you type:

 sudo <command>

you are running as root user, the requested password is your password. Only your uid is changed and the environment is the same as your user.

When you type:

 su

su command without parameter allow user to become superuser. In this case the requested password is about root.

When you type:

 sudo su

you are running su as root user, sudo ask your password and su does not. So you can become root without knowing the password.

Caution: It is strongly recommended to not use this command unless you really know very well what you are doing

If you want exec command as another user login shell environment:

 sudo su - <user> -c <command>

or

 sudo -u <user> -i <command>

Hi Why not open a terminal Ctrl + Alt + T and type man su? That will explain what the su command does.

Similarly with bash.

man = manual and it gives a list of arguments that can be used with the command.
