3 answers
Your school subject is some kind of science.
Power is not one of the basic seven SI units. Anything not one of the original seven can be obtained in terms of one or more of the seven basic units. Those are called "derived units".
For example Joules is Force*distance
= mass * acceleration * distance
kg m/s^2 * m = kg m^2/s^2
= mass * acceleration * distance
kg m/s^2 * m = kg m^2/s^2
