刚刚更新 编辑: 浏览次数:225 移动端

  现在美国大学通常都会要求考生提供SAT2成绩,中国考生一般都选择比较有优势的数学、物理、化学这三门课程,SAT2的物理涵盖了初高中所有的物理知识,但题目大多十分基础,也需要同学们去记一些物理公式,下面小编为大家介绍下SAT2物理考试常见的公式有哪些。

  1、SAT2物理热力公式:

  Physics Formulas - Thermodynamics

  Heat added or emoved: Q = m·c·ΔT

  Change in Internal Energy: ΔU = Q - W

  Boyle&aposs Law: P1V1 = P2V2

  Charles&aposs Law: V1/T1 = V2/T2

  Efficiency of a heat engine(%): E = (W/Qhot)·100

  2、SAT2物理光波学公式:

  Physics Formulas - Waves and Optics

  Snell&aposs Law: n1·sin(θ1) = n2·sin(θ2)

  Wave speed: v = λ·f

  Velocity of light: v = c/n

  Magnification: m = -di/do

  Law of Rlection: θrlection = θincidence

  Mirror and lens equation: 1/d1 + 1/d1 = 1/f

  3、SAT2物理现代物理公式:

  Physics Formulas - Modern Physics

  The energy of a photon: E = h·f

  Matter wavelength: λ = h/p

  Relativistic factor: γ2 = 1/(1 - v2/c2)

  De Broglie Wavelength: λ = h/(mv)

  Half life of radioactive material: Thalf = ln(2)/λ

  Mass energy equivalence: E = mo·c2

  4、SAT2物理电磁学公式:

  Physics Formulas - Electricity and Magnetism

  Electric Fields and Forces Formulas

  Coulomb&aposs Law: F = k·q1·q1/r2

  Electric field of a charge q: E = k·q/r2

  Work done by electric field: W = q·E·d

  Electric field between two metallic plates: E = V/d

  5、SAT2物理光学公式:

  Snell&aposs Law: n1·sin(θ1) = n2·sin(θ2)

  Wave speed: v = λ·f

  Velocity of light: v = c/n

  Magnification: m = -di/do

  Law of Rlection: θrlection = θincidence

  Mirror and lens equation: 1/d1 + 1/d1 = 1/f

  以上就是小编为大家介绍的SAT2物理考试常见的公式有哪些,主要的还是要考同学们去记住这些公式,同学们可以在做SAT2物理备考题的时候记住这些公式,也可以单独的抽出一部分的时间来记住这些公式。只有记住了这些公式,才不会在SAT2考试得时候,因为没记住公式而失分。
