An oscillator refers to any system that exhibits periodic motion around an equilibrium position.
Picture yourself riding on a roller coaster. As it goes up and down, your body moves back and forth repeatedly. In this analogy, you are like an oscillator experiencing periodic motion.
Periodic Motion: Periodic motion refers to any type of repetitive movement that occurs over regular intervals of time.
Harmonic Motion: Harmonic motion describes oscillatory behavior where restoring forces are proportional to displacements from an equilibrium position.
Damping: Damping refers to the gradual decrease in amplitude of an oscillating system over time due to energy dissipation.
