📚 Key Facts — Gravitational Potential Energy
What it is: Energy stored in an object due to its position in a gravitational field — essentially, how high it is above a reference point.
Key relationships:
- GPE ∝ mass — double the mass, double the GPE (directly proportional)
- GPE ∝ height — double the height, double the GPE (directly proportional)
- GPE ∝ g — same object at same height on Moon has 1/6 the GPE as on Earth
The reference point:
- GPE is always measured relative to something — usually the ground
- What matters is the HEIGHT CHANGE, not absolute position
- An object can have negative GPE if it's below the reference point (e.g., down a well)
