terminal velocity
Terminal velocity is when you are diagnosed with going the maximum speed in a defined direction using only gravitational potential. It is life threatening as it is a terminal disease.

Velocity Vapor
Another go to nic spot for OU tards. This place is HELLA slept on because not enough people know about it even though it is BY FAR the BEST nic spot in Norman. The inside of this place looks clean af, as soon as you walk in, you'll see a big ass fish tank (which apparently happens to be a common theme among nic spots in Norman) and you'll see a lounge area with a straight up vape bar. This place is definitely the spot and also happens to have the best prices in town.
I went to Velocity Vapor the other night and I thought I was gonna be in and out of that hoe but I was surprisingly the only there so the owner invited me to play pool with him at the pool table so I spent over an hour there just playing pool and blowing PHAT clouds.

Escape Velocity
Escape Velocity:
.
if you throw an object straight up, it will rise until the the negative acceleration of gravity stops it, then returns it to Earth. Gravity's force diminishes as distance from the center of the Earth increases, however. So if you can throw the object with enough initial upward velocity so that gravity's decreasing force can never quite slow it to a complete stop, its decreasing velocity can always be just high enough to overcome gravity's pull. The initial velocity needed to achieve that condition is called escape velocity.
.
From the surface of the Earth, escape velocity (ignoring air friction) is about 7 miles per second, or 25,000 miles per hour. Given that initial speed, an object needs no additional force applied to completely escape Earth's gravity

1/2 mv2 = GMm/R
.
Where m is the mass of the object, M mass of the earth, G is the gravitational constant, R is the radius of the earth, and v is the escape velocity. It simplifies to:
.
v = sqrt(2GM/R)
.
or
.
v = sqrt(2gR)
.
Where g is acceleration of gravity on the earth's surface.
.
The value evaluates to be approximately:
.
11100 m/s
40200 km/h
25000 mi/h

Blexas
Texas is categorized as a swing state in presidential elections, but has voted for Republicans more times than for Democrats in recent history. As such, as demographics change political alignments, some Democrats believe that Texas will vote blue, or Democratic, due to their Hispanic and African American voters, who often align themselves with the Democratic Party's liberal wing.
Blexas has been cited as possible in the upcoming decades, but only if Democrats continue to win the Hispanic vote in bigger margins.

Ratfucker
Brought to public attention by Bob Woodward and Carl Bernstein in the book on the fall of Richard Nixon, All The President’s Men, ratfucker was Nixon’s term for a political operative who sows chaos among opponents; an agent provocateur. It is thought to have originated among campus political rivalries at USC, and seems to have some usage in the US military.
Along with Nixon’s other ratfuckers, Roger Stone caused fights at otherwise peaceful Democratic Party protests to generate a false narrative that the Democrats were violent and dangerous.

That ol' gal of mine drives the 12 lane freeway during the week and a John Deere on the weekends. She likes opra and the Grand Ol' Opry. I love them countrypolitan women.
