Is the power head the same as a pump? Also do power heads work for smaller aquariums and pumps for big and small?

A powerhead is a pump, but it just circulates water. A pump circulates water, usually as a secondary benefit to what it is primarily used for.
If the goal is to drive a protein skimmer or return water from a sump into the main tank, that would be a pump. If the goal is to circulate water inside the tank, the powerhead is a pump designed to do that.

Pump= moves water from point "A" to point "B".
Powerhead= moves water around.

Oh, thanks for the clear discription.

Also some power heads are built to move water around and some are made to help oxygenate the water through the use if a Venturi. That puts air into the water really well
