![]() So every oscillator hasĪn equilibrium position, and that would be the point at which there's no net force on the Like the name suggests, tries to restore this system, but restore it to what? Restore the system to Share this common fact, that they all have a restoring force. So you could ask why do these things oscillate in the first place, and it's because they all Masses on springs, pendulum, but there's many other examples and all those examples share one common feature of why they're an oscillator. Going back and forth, that's an oscillator. Mass connected to a string, and you pull the mass back and then it swings back and forth. ![]() Or another common example is a pendulum, and a pendulum is just a Pull this mass back, it's gonna oscillate back and forth, and that's what we mean by an oscillator. ![]() So for instance, a mass on a spring here is an oscillator if we And what an oscillator is is an object or variable that can move back and forth or increase and decrease, go up and down, left and right, over and over and over.
