Gravity

You will. In toward the big one...

Gravity is the force that attracts two bodies toward each other, the force that causes apples to fall toward the ground and the planets to orbit the sun. The more massive an object is, the stronger its gravitational pull.

Fundamental force
Gravity is one of the four fundamental forces, along with the electromagnetic, strong and weak forces.

It is what causes objects to have weight. When you weigh yourself, the scale tells you how much gravity is acting on your body. The formula for determining weight is: weight equals mass times gravity. On Earth, gravity is a constant 9.8 meters per second squared, or 9.8 m/s2.





Historically, philosophers such as Aristotle thought that heavier objects accelerate toward the ground faster. But later experiments showed that wasn't the case. The reason that a feather will fall more slowly than a bowling ball is because of the drag from air resistance, which acts in the opposite direction as the acceleration due to gravity.

Newton's Law of Universal Gravitation says that the force of gravity is directly proportional to the product of their masses and inversely proportional to the square of the distance between them

Sir Isaac Newton developed his Theory of Universal Gravitation in the 1680s. He found that gravity acts on all matter and is a function of both mass and distance. Every object attracts every other object with a force that is proportional to the product of their masses and inversely proportional to the square of the distance between them. The equation is often expressed as:

Fg = G (m1 ∙ m2) / r2

• Fg is the gravitational force
• m1 and m2 are the masses of the two objects
• r is the distance between the two objects
• G is the universal gravitational constant

Newton's equations work extremely well to predict how objects such as planets in the solar system behave.

With that being said, when the busty waitress bends over you table and you get a boner, that is not gravity. That is you fixing be devoid of a BIG tip!

Ha ha!

Not falling for it.

Hmm...

Here's one of the great mysteries about gravity.

"It is an unclear forces, but many have tried to explain it through gravitons (invisible particles), cosmic strings, and gravity waves. This force cannot be switched off at any moment; even attempts in an anti-gravity chamber have yet to be successful. Although none of these experiments have come to any proven conclusions, it goes to show how unique and yet principled gravity" is.

 

[miketx]

Hmm...

No, libtard, it has to do with objects in ORBIT. Larger things IN ORBIT will affect the trajectory of smaller things IN ORBIT.

Go back to watching the Flintstones.

Plainly put, gravity is something that we know for a fact exists, and something that we haven't "proven" yet (I.e. directly observing the theorized Gravitons).

Also, there is no such thing as "empty" space in this three dimensional existence.

 

[james bond]

Well according to science, gravity is the bending of "space-time".

Mkay, how do you bend empty space?

According to Einstein, it is a bend is spacetime. One Nobel Prize isn't enough for AE

.

 

[james bond]

Newton, supposedly would not have understood this "during his time" as he thought it was a straight line attraction between two masses.

However, understanding it as a bend in spacetime it could lead us to... I know it sounds wild and crazy... TIME TRAVEL.

"Einstein's General Theory of Relativity and Time Travel

In Einstein's Special Theory of Relativity, he addressed motion in reference frames which were in relative uniform motion with respect to each other (frames in which the laws of physics were the same and the speed of light was the same, inertial frames). However, what happens if the reference frames are accelerated with respect to each other, that is, the relative velocity between the frames is changing (as occurred in the Twin Paradox)? To handle this, Einstein developled his General Theory of Relativity. In Einstein's GTR, he allows space and time to not only be distorted as in Special Relativity, but he allows for space and time to be curved (and not flat, Minkowski space). GTR couples the Laws of Motion and Gravity (and other forms of energy)."

If Gravity is a force there are huge problems, because that conflicts with the rest of physics (=nonsense)

If it is a FORCE then where is the POWER coming from?
If it is a FORCE how does that work at a distance.?
If it is a FORCE why is the POWER not reduced?


Of course the universe is not held together by gravity at all

 

[I amso IR]

What in the hell is it?

Gravity aka Grabity is a downer!

 

[I amso IR]

Down we come, from the wild blue yonder! Yeech!

 

[Confounding]

Mkay, how do you bend empty space?

Very carefully I imagine.

If the ball is falling at, for example, a speed of 10.0 m/s, then it's velocity is v = -10.0 m/s. Since g = -9.8 m/s2, then 1 second later we have v = -19.8 m/s Note that -19.8 is less than -10.0 ... so velocity has decreased, even though the speed has increased from 10.0 to 19.8 m/s. Hope that helps clear things up.

Reference Is the acceleration due to gravity positive or negative

With reference to gravity, here is an interesting little bit of information. A lesson in how to do more with less. Ain't physics fun?

 

[Votto]

Well now that we have found out that gravity flows in waves, then we know that what we perceive to be "empty space" is incorrect.

It is more like swimming in an ocean, but an ocean of what exactly?

LOL. No, the velocity has not decreased, but the potential energy has.
