I need to calculate the power required for an object to hover. So I need to find the power needed to maintain an upwards force of mg on the object (not using any fixed object, relying on the air for newton's third law) , and I'd much rather do it without considering the object's method of propulsion..
The Attempt at a Solution
No equations i can find are suitable and the fact that the object won't move leaves me very confused wrt units. I can't see where I'm gonna pull Nm/s as a unit out of, but intuitively it requires energy to stay up in the air...
