Suppose you lift a suitcase from the floor to a table. Does the work you do on the suitcase depend on (a) whether you lift it straight up or along a more complicated path, (b) the time it takes, (c) the height of the table, (d) the weight of the suitcase ? Repeat the parts (a) to (d) for the power needed rather than the work.
