Homework Help: Simple harmonic movement

  1. Feb 5, 2010 #1
    Hi,
    could some one please explain in detail why this things are true?

    thanks

    A simple pendulum suspended in a rocket ship has a period T0. Assume that the rocket ship is near the earth in a uniform gravitational field.

    True: If the ship accelerates downward at 9.81 m/s2, the pendulum will no longer oscillate.
    False: If the ship accelerates upward, the period increases.
    True: If the length of the pendulum is doubled, the new period will be the square root of two times T0.
    False: If the mass of the pendulum is halved, the period decreases.
    False: If the ship moves upward with a constant velocity, the period increases.
