在SAT II 物理考试常用的公式有：

　　The Kinematic Equations apply to one-dimmensional motion with costant acceleration from point 1, situated d1 from a point of reference to point

　　2, situated d2

　　from the same point of reference. v1 is the velocity at point 1 and v2 is the velocity at point 2. v2 = v1 + a·t

　　d2 = d1 + (v1 + v2)·t/2 d2 = d1 + v1·t + a·t2/2

　　d2 = d1 + v2·t - a·t2

　　/2 v22 = v12 + 2a(d2 - d1)

　　Average velocity: vav = Δd/Δt Average acceleration: aav = Δv/Δt

　　Rotational kinematics equations with constant angular acceleration:

　　ω2 = ω1 + α·t

　　Φ2 = Φ1 + (ω1 + ω2)·t/2 Φ2 = Φ1 + ω1·t + α·t2/2 Φ2 = Φ1 + ω2·t - α·t2/2 ω22 = ω12 + 2α(Φ2 - Φ1)

　　Average angular velocity: ωav = Δθ/Δt Average angular acceleration: αav = Δω/Δt Frequency: f = ω/2π Period: T = 2π/ω

　　Relations between angular and linear variables: l = Φ·r v = ω·r a = α·r

　　Dynamics Formulas

　　Pressure: P = F/A

　　Newton's Second Law: F = m·a

　　Force of kinetic friction: Ff = μ·N Hooke's Law: F = -k·x

　　Centripetal Force: Fc = m·v2/R Centripetal acceleration: ac = v2/R

　　Work, Energy, Conservation Laws Formulas

　　Work: W = F · d = Fdcos(α) Potential Energy: PE = m·g·h Kinetic Energy: KE = m·v2/2 Mechanical Energy: E = KE + PE Instantaneous Power: P = F·v The Work-Energy Theorem: W = ΔKE

　　Gravitation Formulas

　　Newtonian gravity formula: Fg = G·m·M/R2 Kepler's Third Law: T2/a3 = ct.
