Posted on Feb 26, 2013 # 39 People Who Just Learned Gravity Is A Bitch

**Sir Isaac Newton would be proud.**

##
1.
Everyone has to learn about gravity sometime!

##
2.
Some people learn about it when they're young.

##
3.
Some people learn about it when they're old.

##
4.
This co-ed just learned that gravity causes you to accelerate at 9.8 meters per second squared.

##
5.
This young man just learned that that is really fast!

##
6.
This tree just taught this gentleman that all falling objects travel at 9.8 m/s squared, regardless of size.

##
7.
So gravity is a great equalizer.

##
8.
Sir Isaac Newton was the first to accurately describe how gravity works in 1690. This boy just figured it out in 2013.

##
9.
Newton's gravitation equation is F = Gm1m2/r2.

##
10.
Where "F" is the force due to gravity, between two masses.

##
11.
Which are a distance "r" apart

##
12.
"G" is the gravitational constant that will always be there.

##
13.
This cat just learned that gravity is dependent on mass differential.

##
14.
And the young man in the middle just learned the force of gravity is dependent on distance between objects.

##
15.
Acceleration due to gravity on the surface of the earth is g = GM/r2.

##
16.
Where "M" is the mass of the Earth.

##
17.
And "r" is the radius of the Earth (or distance between the center of the Earth and you, standing on its surface).

##
18.
And "G" is the gravitational constant.

##
19.
These two making out just learned about gravitational acceleration!

##
20.
Einstein’s theory of general relativity (GR) is Gμν = 8πG/c4 Tμν.

##
21.
It is a very accurate theory of gravity.

##
22.
Where "G" (without the subscripts) is the gravitational constant.

##
23.
And "c" is the speed of light.

##
24.
This young lady just learned that Einstein was right!

##
25.
Gravitational Potential Energy is Eg = mgh.

##
26.
Where "m" is mass of object...

##
27.
..."g" is acceleration due to gravity...

##
28.
..."Eg" is the amount of gravitational potential energy an object has when it is near the surface of the Earth...

##
29.
...and "h" is height of object above the surface of Earth.

##
30.
Marines now know about gravitational potential energy!

##
31.
Large objects in the universe are also subject to gravitational acceleration: a = √(GMa0/r)

##
32.
Where where "a" is the acceleration an object feels...

##
33.
..."M" is the mass of a galaxy...

##
34.
..."r" the distance between the object and the center of the galaxy...

##
35.
...and "G" is the gravitational constant.

##
36.
This cameraman does not appreciate the mass of the universe.

##
37.
Sadly, none of these equations can determine the acceleration of gravity between two bros.

##
38.
So keep it up, guys...

##
39.
You're gonna nail it someday!
