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

WavesEdit

Electromagnetics (electricity)Edit

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