Periodic motion is a type of motion that repeats itself at regular intervals. Examples include the oscillation of a pendulum and the vibrations of a guitar string.

The period ($T$) is the time it takes for one complete cycle of periodic motion.
Frequency ($f$) is the number of cycles per unit time, typically measured in Hertz (Hz).
The relationship between period and frequency is given by $f = \frac{1}{T}$.
Simple harmonic motion is a specific type of periodic motion where the restoring force is directly proportional to displacement.
In a mass-spring system, the period $T$ depends on both the mass ($m$) and the spring constant ($k$), given by $T = 2\pi \sqrt{\frac{m}{k}}$.
