This is a draft cheat sheet. It is a work in progress and is not finished yet.
Forces and Energy

impulse = F∆t = ∆(mv) |
F = ∆p/∆t |
kE = 1/2mv2 |
∆GPE = mg∆h |
W = Fd = ∆E |
W = Fd |
(%) efficiency = (useful energy output) (total energy input) × 100% |
(%) efficiency = (useful power output) (total power input) × 100% |
P = W / t |
P = ∆E/ t |
p = F / A |
∆p = ρg∆h |
T (in K) = θ (in °C) + 273 |
pV = constant |
c = ∆E / m∆θ |
