Question

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.   1) If the ship accelerates downward at 9.81 m/s2, the pendulum will no longer oscillate.  2) If the length of the pendulum is doubled, the new period will be: square root of 2 times T0.  3) If the ship moves upward with a constant velocity, the period decreases.  4)   If the mass of the pendulum doubles, the period increases.  5) If the ship accelerates upward, the period increases.   (TRUE OR FALSE)

Explanation / Answer

3)False: The period is determined by g. g can only change with another acceleration, not a velocity.

4)False: The mass will not change the period. The period depends on length and g.

5)False again: the new acceleration is at least 9.81. If there is an upward acceleration, 9.81 is included in that because 9.81 must be overcome.

2)True.

1)False. There is still an acceleration on the body and that is g.
