What is the relationship (direct or inverse) between

Power and time

Power and force

Power and speed

Power and work

The relationship between power and time would be an inverse one. The relationship between power and force would be a direct one as per the equation P = Fd/t. Knowing this we can solve for speed as s = d/t. P = Fv, here we can see that there is a direct relationship between power and speed. Finally since F•d is another way to define work, the equation becomes. P = W/t. This would also be a direct relationship between power and work.
