　　SAT II物理力学常见公式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 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
