Question

An astronaut on the moon has two science experiments. One is a masson a spring, the other a simple pendulum. On the moon, the periodof oscillation is one second for both experiments. When she returnsto earth and repeats the experiments, which one of these statementsis TRUE?
(A) Both experiments have the same period, but it is now longerthan one second.
(B) Both experiments have the same period, which is shorter thanone second.
(C) The pendulum has a period shorter than one second and the masson spring has a period of one second.
(D) The pendulum has a period of one second and the mass on aspring has a period greater than one second.
(E) The pendulum has a period greater than one second and the masson the spring has a period of one second.

Explanation / Answer

A pendulum's period is related to gravity (which is therestorative force). The greater the gravity, the faster thependulum swings. The period is T = 2(l/g). . In contrast, a spring oscillation is only dependent on thespring (which is the restorative force) and the mass. Itdoesn't change. It's period is T = 2(m/k). That said: a.False b.False c. False d. False e. True
