Potential Energy
Also known as: PE, stored energy
Energy stored in a system due to the position or configuration of its parts, ready to be released. Explains why water behind a dam can generate electricity and why stretched springs snap back.
💡 Intuition
Energy waiting to be released—like a stretched rubber band or a ball held high.
Core Idea
Potential energy is relative—you need to define a reference point (like the ground).
🔬 Example
🎯 Why It Matters
Explains why water behind a dam can generate electricity and why stretched springs snap back.
⚠️ Common Confusion
PE can be negative if the object is below your chosen reference point — the reference is arbitrary.
