i had a discussion with some guy on facebook
over this when I was 9 years old...
would you say the reason water flows downhill is due to gravity or potential energy? i said it was gravity, but he went "what? no, it's because of potential energy."

when I was 12 I was arguing with some guy on iFunny. He randomly brought up the fact that fucked his friend’s dad, and that he didn’t even give him a reach around

I mean, it's due to gravitational potential energy, so both views are kinda right

Unless your discussion was about which way was better in explaining to people

>Gravitational potential energy is the potential energy a massive object has due to its position in a gravitational field. It is the mechanical work done by the gravitational force to bring the mass from a chosen reference point (often an "infinite distance" from the mass generating the field) to some other point in the field, which is equal to the change in the kinetic energies of the objects as they fall towards each other.
You were both saying the same thing. But technically "gravity" is the more-correct answer because "potential energy" encompasses more than gravitational potential energy.

The potential energy comes from gravity. So the guy was a retard. Without gravity there is no energy gradient to cause the water to move downhill.

But gravity is a force, not energy.

Just stop saying gravity

Does water keep flowing downwards?

Does it keeps flowing downwards on zero gravity?

Is there gravity on space?, if not why the earth don't crash into moon?

You learn that in physics 101.
>Gravity is a conservative force, you can define a potential energy (field) for any conservative force.

The PE is the integral of the force * movement, just a consequence of that force

Gravity is an acceleration

Other guy's view is wrong because he said, "no."

So how old are you now?

First, I don't think you're old enough to be here.
>Does water keep flowing downwards?
There is no "downwards," water on earth is attracted to the center of gravity of the planet, as are you.
>Does it keeps flowing downwards on zero gravity?
There is no "downwards." If there is no gravity there would be nothing for the water to be attracted to. But from our understanding of the universe there is always gravity.
>Is there gravity on space?, if not why the earth don't crash into moon?
There is gravity everywhere, masses always attract each other. The moon has sufficient momentum to just overcome earth's gravity vector and be locked into orbit. The current explanation of why everything hasn't condensed into one point is that forces from the big bang are still propelling matter away more than gravity is pulling everything back. But we don't know if gravity works the way we think it does or if the big bang actually happened, so take it with a grain of salt but it's the 'best' theory right now.

>no downwards
The idea of "down" is relative to the observer.
You are being attracted to X star in Alpha Centauri right now, but you probably wouldn't call "down" the direction of that gravity vector because you're on earth.

These are literally the same answer.

Stop guessing start learning No. 16276637

You two idiots are arguing about the same phenomenon. It’s stored potential energy at the peak of the area where it’s about to fall. It’s gravity that pulls it forward due to uneveness of the terrain.

So going up a hill =stored potential energy

Falling down the hill = gravity.

Learn proper language skills so things can be clearly defined.

Both of you idiots are correct but both of you didn’t bother fact checking yourselves with a simple google search.

Neither, because neither gravity nor potential energy are actual forces but abstract derivations

Electrostatics make all heavenly body want to be round. A landslide is no different than a river. All mass is trying to get to the center of the Earf.
