1. Données g = 9,81 m/s^2 1kWh = 3600 x 1000 J 1Pa = 1 N/m^2 1bar = 10^5 Pa tr/min x 2π/30 = rad/s

2. Th = temps haut ( s ) T = période ( s )

3. Autre f = 1/T α = Th/T η = Pu/Pa

4. Mécanique

4.1. Translation P = F.v E = F.v

4.2. Rotation P = C.ω

4.2.1. Unités ω = rad/s C = N.m P = W E = Wh ou J F = N Poids = N v = m/s p = Pa Q = m^3/S m = kg h = m

4.3. Autre F tan = C/R Poids = m.g p = F/S P = Q.p E = m.g.h

5. Electrique

5.1. Continue P = U.I E = P.Δt

5.2. Alternatif P = U.I.cos α

5.2.1. Unités P = W E = Wh ou J α = ° U = V I = A Q = Ah Δt = s

5.3. Autre E = U.Q.% R = U/I
