Physics Formulas – Mechanics Kinematics Formulas The Kinematic Equations apply to one- dimmensional motion with costant acceleration from point 1, situated d 1 from a point of reference to point 2, situated d 2 from the same point of reference. v 1 is the velocity at point 1 and v 2 is the velocity at point 2. v 2 = v 1 + a·t d 2 = d 1 + (v 1 + v 2 )·t/2 d 2 = d 1 + v 1 ·t + a·t 2 /2 d 2 = d 1 + v 2 ·t - a·t 2 /2 v 2 2 = v 1 2 + 2a(d 2 - d 1 ) Average velocity: v av = Δd/Δt Average acceleration: a av = Δv/Δt Rotational kinematics equations with constant angular acceleration: ω 2 = ω 1 + α·t Φ 2 = Φ 1 + (ω 1 + ω 2 )·t/2 Φ 2 = Φ 1 + ω 1 ·t + α·t 2 /2 Φ 2 = Φ 1 + ω 2 ·t - α·t 2 /2 ω 2 2 = ω 1 2 + 2α(Φ 2 - Φ 1 ) Average angular velocity: ω av = Δθ/Δt Average angular acceleration: α av = 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
