P = V x I. Power = Voltage x Current.
E = V x I x t. Energy = Voltage x Current x time.
V = I x R. Voltage = Current x Resistance.
Q = I x t. Charge = Current x time.
W = F x d. Work done = Force x distance.
W = E. Work done = Energy transferred.
s = d ÷ t. speed = distance ÷ time.
a = (v-u) ÷ t. acceleration = change in velocity ÷ time.
p = m x v. momentum = mass x velocity.
w = m x g. weight = mass x gravity.
p = F ÷ a. pressure = Force ÷ area.
d = m ÷ v. density = mass ÷ volume.
v = f x λ. wave speed = frequency x wavelength.
