Kinematics

The study and description of how physical bodies move

The Big Four Formulas

The following formulas work when the acceleration $a$ is constant.

$v = v_0 + at$

$v = \frac{1}{2}(v_0 + v)t$

$s = s_o + v_{0}t + \frac{1}{2}{a}t^2$

$2as = v^2 - v_0^2$ Comes from energibevaring

$\sin{(v_0 + at)}dt = v_{0}t + \frac{1/2}at^2 + s_0$

Air resistance

$F_d = \frac{1}{2}C \cdot p \cdot A \cdot v^2$

C = motstandskoeffisient
p = tetthet
A = frontareal
v = fart
