Simple harmonic motion (HSC SSCE Mathematics Extension 2): Flashcards

Oscillatory motion with acceleration toward a fixed point.

x(t) = A cos(ωt + φ)

v(t) = -Aω sin(ωt + φ)

f = 1/T

The greatest distance from the equilibrium position.

KE = 1/2 mω²A² cos²(ωt)

PE = 1/2 kx²

Constant, as KE and PE transform into each other.

T = 2π√(L/g)

Used in pendulums and spring-mass systems.
