| 2. | Canadian Change-Up | ||
|
Fondly named after one infamous french-canadian, changing the order of rotation during a session by passing the piece in the incorrect direction. Hoover grimaced as he realized his egregious error of passing the dutchie an the right hand side, fulfilling his first error of a canadian change-up

| 3. | california lane change | ||
|
When you are driving on the highway and shift across all the lanes in either direction.
Similar to a jersey slide Im in the right lane and i want to pass everyone, I think I'll do a california lane change to the left and then a jersey slide to exit

| 4. | velocity | ||
|
Defined as the change in position of an object (displacement) per unit of time. Velocity, unlike speed, takes into account the direction of travel relative to a base point.
v = s/t (where v and s are vectors) Where (using SI units): v is the velocity of the body in metres per second (ms^-1) s is the displacement of the body in metres (m) t is the time taken to travel from the initial point to the final point in seconds (s) 1. (One dimension) If you start at point A and travel directly north to point B which is ten metres away, and it takes you five seconds to get there, your velocity will be 2ms^-1 due north.
2. (One dimension) If you travel west for a ten seconds at 1ms^-1, take a break for twenty seconds and then travel for another ten seconds at 1ms^-1, your velocity for the trip will be .05ms^-1 due west. 3. (Two dimension) If you start at point A and travel north at 3kmh^-1 for two hours, and then instantaneously change direction and travel due east for four hours at a speed of 2kmh^-1 to point B, your velocity for the trip is 10kmh^-1 N53°E (53°T) I think... |

| 5. | acceleration | ||
|
Defined as the change in velocity over a period of time. Acceleration is a vector quantity and therefore is stated as a quantity with a direction.
a = (v-u)/t (where a, v and u are vectors) Where (using SI units): a = acceleration of the body in metres per second per second (ms^-2, or metres per second squared) v = final velocity of the body in metres per second (ms^-1) u = initial velocity of the body in metres per second (ms^-1) t = time period between the initial and final velocity, in seconds (s) An accelerating body can also be decelerating (ie, negative acceleration) or be at rest. Also, instantaneous acceleration is a bit different. 1) A car that is travelling at 2ms^-1 changes its speed to 6ms^-1 over a period of five seconds, and doesn't change direction. During that five seconds, it had an average acceleration of .8ms^-2 in initial direction.
2) A car travelling forwards at 2ms^-1 is suddenly put into reverse and five seconds later it is travelling 2ms^-2 backwards. It's average acceleration is .8ms^-2 backwards (-.8ms^-2 forwards). Note in this example, the car would have been temporarily at rest just when it changes direction. It is still accelerating (in negative direction, ie backwards, ie decelerating) during this period. |

| 6. | Weathervane | ||
|
A politician who has a frequent change of opinion. Flip flopper So named because both always change direction. Mitt Romney has become a weathervane since running for president.

| 7. | fuctuate | ||
|
1. Changing direction or course wildly and without any fucking rhyme or reason. "What's wrong with her? Dude who knows... her mood fuctuates so often, I don't even try to keep up."
note: Redneck dictionary usage ( typically after someone lets out a particularly nasty round of flatulence ) "Good Lord Bubba!! What the fuct-u-ate!??" |
