Classical mechanics (movement)

General Form: $A=B\times C$ use the "algebra pyramid" to rearrange the equation respectively

$force=mass\times acceleration$
$weight=mass\times acceleration_{duetogravity}$
$density={\frac {mass}{volume}}$
$acceleration={\frac {v_{f}-v_{i}}{t_{f}-t_{i}}}$
$velocity={\frac {distance}{time}}$
$distance={\frac {acceleration_{duetogravity}\times time^{2}}{2}}$ (for something that is falling. usually the y component)
$displacement=Originalvelocity\times time+{\frac {1}{2}}acceleration\times (time^{2})$

Kinetic and potential energy

$kineticenergy={\frac {mass\times velocity^{2}}{2}}$
$potentialenergy=mass\times acceleration_{duetogravity}\times h$
$momentum=mass\times velocity$
$I=F\times T$

Waves

Speed = Distance/Time s = d/t Velocity = Frequency * Lambda v=f*ʎ

Electromagnetics (electricity)

$power=voltage\times current$
$current={\frac {voltage}{resistance}}$
