  1. Equations
    1. density = m/v
      1. energy transferred = charge flow x potential difference
        1. time = energy transferred/power
          1. weight = mass x gravitational field strength
            1. g = w/m
              1. m= w/g
            2. work done = force x distance
              1. d = w/f
                1. f = w/s
              2. force = spring constant x extension
                1. spring constant = f/e
                  1. e = f/ spring constant
                2. moment = force x distance
                  1. f= m/ d
                    1. d= m/f
                  2. pressure = force/ area
                    1. f= p x a
                      1. a = f/p
                    2. distance = speed x time
                      1. v = d/t
                        1. t= d/v
                      2. acceleration = change in velocity/ time
                        1. CIV = a x t
                          1. t = CIV/ a
                        2. resultant force = mass x acceleration
                          1. m= f/a
                            1. a = f/m
                          2. momentum = mass x velocity
                            1. m = p (velocity) /m
                              1. v = p/m
                            2. kinetic energy = 0.5 x mass x velocity²
                              1. m = 2ek/ v²
                                1. v = (square root) 2ek/m
                              2. gpe = m x g x h
                                1. m= gpe/ (g x h )
                                  1. g= gpe / (m x h)
                                    1. h = gpe / (m x g)
                                2. power - energy transferred/ time
                                  1. e = p x t
                                    1. t= e/ p
                                  2. power = work done/ time
                                    1. w= p x t
                                      1. t= w / p
                                    2. efficiency= total input / useful output
                                      1. useful output= efficiency x total input
