## Classical mechanics (movement)Edit

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

• $force = mass \times acceleration$
• $weight = mass \times acceleration_{duetogravity}$
• $F = m \times a$
• $density = \frac{mass}{volume}$-
• $acceleration = \frac{v_f-v_i}{t_f-t_i}$
• $velocity = \frac{distance}{time}$
• $distance = \frac{acceleration_{duetogravity} \times time ^ 2}{2}$ (for something that is falling. usually the y component)
• $displacement = Original velocity \times time + \frac{1}{2} acceleration \times (time ^ 2)$

## Kinetic and potential energyEdit

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

## Electromagnetics (electricity)Edit

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