comment Exactly how much lift is needed to overcome the weight of an average person?
@User58220 The kilogram. In the case of the fps system, as I was taught, pound is a unit of force (weight) and there is no corresponding fps mass unit

@Dilaton yes. Try to improve the question up to plicy before flagging, though.

Cleaned up and reopened due to change of policy.

@User58220 My bad, you're correct, the pound is a unit of mass. Strange; I was explicitly taught that the pound was a unit of weight and not mass.

@User58220 Nope. Pound is a unit of weight, kilogram is a unit of mass. The metric system's corresponding unit of weight is kilogram-force, though you can of course use Newton.

comment How do voltage and voltage drops over a circuit relate to work done?
@user1299028 The current changes. Don't draw parallels with mechanics, voltage doesn't work that way.

comment How do voltage and voltage drops over a circuit relate to work done?
@user1299028 A potential difference of 10V does not exert the same force. You're thinking about electric field. A potential difference of 10V is defined to be such that the work done does not change. (Well, not exactly,it is defined as a line integral, but it turns out to be conservative for curl-less fields)

"I must increase the voltage"-- to do what?

comment What happens when a black hole dies?
Black holes do die, but gradually. Your question is a bit scattered, please try to ask only one question per post.

I meant that you should edit that into the answer :) Comment are temporary.

comment Momentum conservation problem
Could you expand on the answer and explain why it fits the situation?

comment Causes of hexagonal shape of Saturn's jet stream
I've already answered this question here, though I won't repost it as hdhondt already has addressed the issue with the same reference.

comment How can I calculate out the 'specific charge' of an atom?
@BrandonEnright Not really, but I would close it anyway because it is essentially asking for a walkthrough, which we don't do here.

comment Why the dissolution of hydrophobic compounds decreases the entropy of water molecules in the vicinity of the solute?
We do address physical mechanisms on Chemistry.SE :) Crossposts/migrations are discouraged if the post is on topic on one site, however if it does not get answered in a couple of days I'd be happy to migrate it for you.

comment Is there a momentum for charge?
@MartinJ.H. True, but the monopole moment is a scalar. And I'm talking about the center of charge proposed by the OP above; $\sum q\vec r$ is the dipole moment

comment Why does a helium filled ballon move forward in a car when the car is accelerating?
As far as the discussion here goes, it would be better if it as held in Physics Chat. Also, it seems to me that this stems from a disagreement as to what "heavier" means. Some are taking buoyant force and drag into account while measuring the heavyness.

@Val, and everyone else: Please be nice. Personal attacks will not be tolerated and will get you suspended. I have edited the message out for now.

comment Do photons age in a medium?
@Tarek Basically, group velocity and phase velocity. The phase velocity of the photons is $c$, the group velocity of the resultant wavepackets is not.
