Simple Harmonic Motion Concepts

The video explores simple harmonic motion, explaining its rules, equations, and characteristics. It covers angular frequency, oscillator motion, and energy transformations. The video also models simple harmonic motion using circular motion and analyzes systems like mass-spring and pendulum. Key concepts include restoring force, equilibrium, and Newton's Second Law. The video concludes with a summary of the main points.

What is the defining characteristic of the restoring force in simple harmonic motion?

• It is constant regardless of displacement.

• It is directly proportional to displacement and points towards equilibrium.

• It is always zero.

• It is inversely proportional to displacement.
