Oscillations x = Acos(ωt + φ) sqrt(k/m) ½ k x 2 = ½ k A 2 cos 2 (ωt + φ) K = ½ m v 2 = ½ m ω2A 2 sin 2 (ωt + φ) E = U + K = ½ k A 2 Equivalent point – slope becomes zero Oscillates around equivalent point when it acquires thermal energy Negative τ – shows moving in direction that makes the angle smaller Small Angle Approximations for Sinusoidal Equations
