Simple Harmonic Motion
Also known as: SHM, oscillation
Repetitive back-and-forth motion where the restoring force is proportional to displacement. Model for waves, sound, electronics, and many natural oscillations.
💡 Intuition
A spring or pendulum that bounces back and forth in a smooth, repeating pattern.
Core Idea
The motion repeats with a specific period that depends on the system, not how far you pull.
🔬 Example
🎯 Why It Matters
Model for waves, sound, electronics, and many natural oscillations.
⚠️ Common Confusion
Period of a pendulum depends on length and g, NOT on mass or amplitude (for small angles).
