Ch. 13 Oscillations About Equilibrium

Ch. 13 Oscillations About Equilibrium. Periodic Motion. Motion that repeats itself over a fixed and reproducible period of time. The revolution of a planet about its sun is an example of periodic motion. The highly reproducible period (T) of a planet is also called its year.

Pendulum

Pendulum. ? rad = x/L. ?. Restoring force: F = -mg sin ?. If ? is small, sin ? ? ?. F = -mg ? = -mg x/L. F = -(mg/L) x. F = -kx. Force constant (k) = mg/L. For small angles, pendulum is SHM. period: T = 2 ? ?(m/k) = 2 ? ?(m/(mg/L)). T = 2 ? ?(L/g).
