Physics Formulas: Law of cosines: c 2 = a 2 + b 2 – 2ab cos θ Law of Sines: (sin A)/a = (sin B)/b = (sin C)/c Average velocity and acceleration defined: v avg d /t a avg v /t Distance, velocity, acceleration and time: d = d o + v avg t d = d o + 1/2(v + v o )t d = d o + v 0 t + (1/2)at 2 v = v 0 + at v 2 = v 0 2 + 2a d Newton’s 2 nd Law: F net = m a Force of friction: F f,k = μ k F N F f,s = μ s F N Period of pendulum: T = 2 π√ (l/g) Centripetal acceleration: a c = v 2 /r Kepler’s 3 rd Law: (T A /T B ) 2 = (r A /r B ) 3 Newton’s Law of Univ. Gravitation: F = G(m A m B )/d 2 Kepler’s 3 rd Law (Newton’s version): T 2 = (4 π 2 / GM)r 3 Orbital velocity: v = GM/r Impulse = F t Momentum: p = m v Impulse mom. them: F t = m v Work: W = Fd cos θ Kinetic Energy: K = 1/2 mv 2 Work Energy Theorem: K = W Power: P = W/t Mechanical Advantage: MA = F r /F e Ideal Mechanical Advantage: IMA = d e /d r Efficiency: e (%) = (W o /W I ) x 100 = (MA/IMA) x 100 Potential Energy:
