Index of useful physics equations

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

$f o r c e = m a s s \times a c c e l e r a t i o n$
$w e i g h t = m a s s \times a c c e l e r a t i o n_{d u e t o g r a v i t y}$
$d e n s i t y = \frac{m a s s}{v o l u m e}$
$a c c e l e r a t i o n = \frac{v_{f} - v_{i}}{t_{f} - t_{i}}$
$v e l o c i t y = \frac{d i s t a n c e}{t i m e}$
$d i s t a n c e = \frac{a c c e l e r a t i o n_{d u e t o g r a v i t y} \times t i m e^{2}}{2}$ (for something that is falling. usually the y component)
$d i s p l a c e m e n t = O r i g i n a l v e l o c i t y \times t i m e + \frac{1}{2} a c c e l e r a t i o n \times (t i m e^{2})$

$k i n e t i c e n e r g y = \frac{m a s s \times v e l o c i t y^{2}}{2}$
$p o t e n t i a l e n e r g y = m a s s \times a c c e l e r a t i o n_{d u e t o g r a v i t y} \times h$
$m o m e n t u m = m a s s \times v e l o c i t y$
$I = F \times T$

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