SAT考试：物理力学公式

　　SAT考试是美国大学留学标准之一，也是美国奖学金评定的标准。今天小编为大家讲解的是SAT考试中的物理，SAT物理考试，相对于国内物理考试是有区别的，国内物理考试注重的是计算和公式运用，但是SAT物理考试相对而言更注重的是生活中的一些物理常识加上学生的多方面发展，在计算这一块并不是重点。虽然不是重点但同学们也是不可忽视的，下面和小编一起看看关于SAT物理考试的力学公式吧。

　　Physics Formulas - Mechanics Kinematics FormulasThe 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/ΔtRotational 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/ωRelations between angular and linear variables:

　　l = Φ·r v = ω·r a = α·r Dynamics Formulas Pressure: P = F/ANewton'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 FormulasNewtonian gravity formula: Fg = G·m·M/R2 Kepler's Third Law: T2/a3 = ct.
