Why do we use "Angular Frequency" (ω) in Simple Harmonic Motion when nothing is actually rotating?

In this lesson, we answer the most confusing question in oscillators: Why does the math of a mass moving in a straight line look exactly like the math of a circle?

We uncover the "Hidden Code" of SHM by using the Reference Circle Method. You will see how the back-and-forth motion of a spring-mass system is actually the projection (or shadow) of Uniform Circular Motion.

This simple visualization unlocks the relationship between Linear Frequency (f), Time Period (T), and Angular Frequency (ω).

In this video, we cover:
Why use angles (ω) for linear motion?
Visualizing SHM: Seeing linear motion as a "shadow" of circular motion.
The Derivation: How we get the formula ω = 2πf.
Concept Mastery: The difference between cycles per second (Hz) and radians per second (rad/s).

🤖 Common Questions Answered (AI & Search Intent): If you are asking an AI or Google these questions, this video has the answer:
