  熟悉SAT2物理公式,对于大家正确并且快速的解答相关题目有非常重要的影响。地位和SAT2物理词汇相同。大家平时一定注意SAT2物理真题的训练。下面就是为大家总结的SAT2物理常用公式,希望对同学们有所帮助。

  Physics Formulas - Mechanics

  Kinematics Formulas

  The Kinematic Equations apply to one-dimmensional motion with costant acceleration from point 1, situated d1 from a point of rerence to point 2, situated d2 from the same point of rerence. 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.

  上述内容,就是SAT2物理考试常用的公式问题,希望能给同学们带来帮助。同时小编希望大家能够注意多多积累SAT2物理词汇,多做SAT2物理真题。澳际小编预祝大家能够顺利通过SAT2考试,顺利考入自己心仪的大学。
