E 1.11 Periodic Motion (Basic Introduction):

"Back and forth Motion"

The motion which the particle repeat the similar condition after a fixed interval of time is called periodic motion.

Key terms of Periodic Motion:

» Oscillation: Repeated back and forth motion over the same path about an equilibrium position.

» Restoring Force: When a body is displaced from its equilibrium position, the force tends to restore it in a equilibrium position. This force is called the restoring force.

» Simple Harmonic Motion: Repetitive 'to and fro' or 'up and down' motion from mean (or equilibrium) position. So the maximum displacement of one side from the mean position is equal to the maximum displacement of other side from the mean position.

» Amplitude: The maximum magnitude of displacement from equilibrium position. It is always positive, denoted by $A$.

» Period: The time to complete one cycle, denoted by $T$. It is always positive.

» Frequency: The number of cycles per unit time, denoted by $f$.

» Angular Frequency: The angular frequency $\omega$ is $2\pi$ times the frequency.
