Presentation Transcript

  1. Pendulum

  2. θrad = x/L θ

  3. Restoring force: F = -mg sinθ If θ is small, sin θ ≈ θ F = -mg θ = -mg x/L F = -(mg/L) x F = -kx Force constant (k) = mg/L

  4. For small angles, pendulum is SHM period: T = 2П √(m/k) = 2 П √(m/(mg/L)) T = 2 П √(L/g) f = (1/ 2 П) √(g/L)

  5. k If the mass on the spring and the pendulum have the same period, what is the length of the pendulum? m1g/k

  6. Energy of a Pendulum θ L PEmax? vmax?

  7. k v M Arrow sticks into block. Maximum compression of spring?
