Answer 2

they are completely different things. Lets us water flowing through a pipe as an illustration.

voltage is like water pressure in a pipe - it determines how fast the electrons will travel through the circuit or how fast water will travel in a pipe

A watt is a unit of power, it can be seen as the total amount of water that is flowing from a pipe.
