Simple Harmonic Motion (SHM) describes oscillatory motion where the restoring force is proportional to the displacement. The period ($T$) is the time it takes for one complete oscillation, while the frequency ($f$) is the number of oscillations per unit time. They are inversely related by the equation $f = \frac{1}{T}$. For a mass-spring system, the period is $T = 2\pi\sqrt{\frac{m}{k}}$, where $m$ is the mass and $k$ is the spring constant. For a simple pendulum, the period is $T = 2\pi\sqrt{\frac{L}{g}}$, where $L$ is the length and $g$ is the acceleration due to gravity. Understanding these relationships is crucial for solving SHM problems.

Complete the following paragraph with the correct terms:
In Simple Harmonic Motion, the restoring force is proportional to the ________. The time it takes for one complete oscillation is called the ________, and the number of oscillations per second is the ________. For a mass-spring system, increasing the mass will ________ the period, while increasing the spring constant will ________ the period.
Consider a scenario where you have two simple pendulums, one on Earth and one on the Moon. How would the period of each pendulum differ, and why? Explain your reasoning, considering the factors that affect the period of a simple pendulum.
