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.

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

Explanation / Answer

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. *If the mass of the pendulum is halved, the period decreases (True or False). False. Mass have no effect on the period *If the ship accelerates upward, the period increases (True or False). the ship accelerates upward so the gravity acceleration of the pendulum feels which increased. so the period is decreased False *If the ship accelerates downward at 9.81 m/s2, the pendulum will no longer oscillate (True or False). True. *If the ship moves upward with a constant velocity, the period increases (True or False).False. no acceleration. *If the length of the pendulum is doubled, the new period will be the square root of two times T0 (True or False). T'=sqrt(2)*T0
