Lessons
Notes:
In this lesson, we will learn:
 The four kinematic equations
 How to choose which kinematic equation to use
 Problem solving with the kinematic equations
Notes:
The four kinematic equations describe the relationship of the initial velocity ($v_{i}$), final velocity ($v_{f}$), acceleration ($a$), displacement ($d$), and time ($t$) for an object moving in one dimension. Each of the equations is made up of four of the five of these variables. If we know three of these variables, we can use the kinematic equations to solve for the two remaining unknown variables.
Kinematic Equations $v_{f}=v_{i}+at$(No $d$)
 $v_{f}^{2}=v_{i}^{2}+2ad$(No $t$)
 $d=v_{i}t+\frac{1}{2}at^{2}$(No $v_{f}$)
 $d=(\frac{v_{i}+v_{f}}{2})t$(No $a$)
$v_{i}$: initial velocity, in meters per second (m/s)
$v_{f}$: final velocity, in meters per second (m/s)
$a$: acceleration, in meters per second squared $(m/s^{2})$
$t:$ time, in seconds (s)
$d:$ displacement, in meters (m)
