1. ### I Formula to calculate amount of force needed to lift/hover

So then to calculate something hovering would acceleration be 9.8 and mass always kilograms?
2. ### I Formula to calculate amount of force needed to lift/hover

No the answer you gave me is what I was looking for I just couldn't find how much it would take to lift 1 gram. I thought it would be around .098 or something like that. But I was wondering if there was a formula so that i just plug in the mass and I get the thrust in newtons.
3. ### I Formula to calculate amount of force needed to lift/hover

Sorry if this I said stupid question but I don't know. So is 1 newton of force required to hover 1 gram?
4. ### I Formula to calculate amount of force needed to lift/hover

I was thinking off building a drone and I was just curious about what the amount of thrust we need to be in order to hover based on weight
5. ### Automotive Propeller powered car questions

I'm trying to build a propeller powered car. Right now I'm trying to find ways to make if faster because I'm limited to a 6 volt battery pack. I was wondering if I used a nozzle shaped design like they do for rockets if it will make it faster or slow it down. The propeller is 6 inches and I was...
6. ### What are the properties of lithium gas?

Thanks for helping. The only reason I asked this on here was because I am not taking physics yet and I have questions that I want answered.
7. ### What are the properties of lithium gas?

Sorry my bad I keep forgetting to add all the important information. I was originally looking into how batteries work. I was doing some research on the anodes and cathodes and how they work. I found that lithium is a anode, then I had and ideas. Now since I don't fully understand how the anodes...
8. ### What are the properties of lithium gas?

I know this may be a dumb question but I don't know it. What I want to know is when lithium is heat and becomes a gas/vapor, does it still have the properties of lithium. Also I know that when water is changed between a liquid, gas, and solid, it always stays as H2O on the molecular level, can...
9. ### How do batteries work?

I have done a decent amount do research on this topic and can't find out about the "magic" that happens in the battery. I know that is is made of cathode which is the positive and anode for the negative with electrolytes in the middle. What I can't find is what anodes and cathodes are made...
10. ### I How does lightning work? (one strike or multiple strikes?)

Something like that. What I am really asking is say you had a thundercloud. It had 1 billion volts stored in it. Now when it discharges, a single or what you said 2 bolts of lighting. What I want to know is,(with the help of man or just by itself) would it be possible for the thunder cloud to...
11. ### I How does lightning work? (one strike or multiple strikes?)

I am mainly asking if it's possible for a thunder cloud to release its sorted energy in burst rather than in one strike. Like if a thundercloud had 1 billion volts would it be possible to great small sparks that allow it to shoot of 5 lighting strikes of different voltages rather than one strike...
12. ### Is it possible for heat to be a physical form?

By physical form I mean stored chemical or actual be a physical thing you can touch. Yes I understand it already is a physical form in atoms but I mean is it possible to have a jar of heat.
13. ### I Is it possible for pure energy to have mass?

So than that makes photons the most basic form of energy or just one of the many types of energy like electromagnetic and kinetic?
14. ### I Is it possible for pure energy to have mass?

When I ask about mass, I am really asking is it remotely possible for pure energy to have mass and possible become so dense it forms a ball with its own gravitational pull. This pull keeps the energy in a ball.
15. ### I How much Gravity is needed to bend light?

By gravity I mean the mass of a object capable of bending light. I don't want a explanation too say about how or why it will bend, just want the mass in numbers or equation please.
16. ### I Is it possible to run as fast as a car?

By run fast I don't mean if the human body can handle it, I mean is there a way to allow a human to reach that speed while running(sort of like the flash)either using some kind of physical or chemical enhancement. Maybe not as fast as a car but some way to increase their max speed without having...
17. ### B What is the true cause of friction?

I know that most friction is caused from rough uneven surfaces rubbing each other, but what is the cause of friction between 2 flat surfaces?
18. ### Is it possible for an atom to have a pure electrical charge?

Oh okay thanks
19. ### Is it possible for an atom to have a pure electrical charge?

An atom is an atom, it can't be impure. If you have a sample of an element, then yes, it will never be 100% pure. Friction has nothing to do with purity. It depends (mostly) on surface roughness. If what you are talking about is a sample (a chunk if it is a solid), then no, it is basically...
20. ### Is it possible for an atom to have a pure electrical charge?

Please don't hate if this is a stupid question, I am a freshmen in high school so I don't know this stuff. What I am really talking about is how all atoms have some impurity in them which is why friction happens, but is there a way to create one with no impurity?
