====== Kinematic Equations ======
  * $V = \frac{\Delta \text{position}}{\Delta \text{time}}$((displacement is the change in position, and velocity is that over time))
  * $V_f = V_i + at$
  * $V_f^2 = V_i^2+2aD$
  * $D = V_it + \frac{1}{2}at^2$
  * $D = V_ft - \frac{1}{2}at^2$
  * $D = \frac{1}{2}(V_f + V_i)t$
Take note of the missing variable for each equation, these don't have to be memorized since they are clearly derived from one root function.

===== Definitions =====
==== Vector ====
A vector quantity includes direction within its value.  Acceleration and Velocity are vector quantities.

==== Scalar ====
Scalar quantities don't, speed is the obvious one.

==== Free Fall ====
When an object is in free fall, gravity is the only force affecting the object. Useful for narrowing forces for calculation.

===== Example =====
> A car starts at rest and accelerates at **3 m/s^2** for **8 seconds**. How far did it go?
==== Variables ====
  * $V_i = 0$ m/s
  * $a = 3$ m/s^2
  * $t = 8$ seconds

==== Equation(s) ====
  * $D = V_it + \frac{1}{2}at^2$
  - $D = 0(8) + \frac{1}{2}3(8^2)$
  - $D = 0 + 96$
  - $\boxed{D = 96 m}$
  * $V_f = V_i + at$
  - $V_f = 0 + 3(8)$
  - $\boxed{V_f = 24 m/s}$
