9. This question has two correct answers. Both must be answered correctly to earn credit. On the Earth a mass is attached to a vertical spring. The mass is held upwards so that the spring is unstretched and then released. Another mass is attached to a string to make a pendulum. The pendulum is pulled over 10° and released. If the spring oscillator and the pendulum were taking to the Moon and set in motion in the same way as before, which of the following would change? A) The spring oscillator's period. B) The pendulum's period. C) The spring oscillator's amplitude. D) The pendulum's amplitude.

Simple harmonic motion
Simple harmonic motion is a type of periodic motion in which an object undergoes oscillatory motion. The restoring force exerted by the object exhibiting SHM is proportional to the displacement from the equilibrium position. The force is directed towards the mean position. We see many examples of SHM around us, common ones are the motion of a pendulum, spring and vibration of strings in musical instruments, and so on.
Simple Pendulum
A simple pendulum comprises a heavy mass (called bob) attached to one end of the weightless and flexible string.
Oscillation
In Physics, oscillation means a repetitive motion that happens in a variation with respect to time. There is usually a central value, where the object would be at rest. Additionally, there are two or more positions between which the repetitive motion takes place. In mathematics, oscillations can also be described as vibrations. The most common examples of oscillation that is seen in daily lives include the alternating current (AC) or the motion of a moving pendulum.
