+ | A harmonic oscillator simply consists of an object attached to a spring and is one of the simplest physical systems we can study. | ||
+ | |||
+ | To describe the system we usually track the $\color{magenta}{\text{position}}$ of the object at the end of the spring. The continuous up and down movement is called an oscillation, which is where the name "oscillator" comes from. | ||
+ | |||
+ | The movement depends crucial on the $\color{red}{\text{properties of the spring}}$. When the spring is harder, the movements of the object will be smaller. In addition, the motion of the object depends on its $\color{blue}{\text{mass}}$. A heavier object will perform larger swings. | ||
