U = mgh
What each symbol means
| Symbol | What it stands for |
|---|---|
| U | Gravitational potential energy relative to chosen reference (J) |
| g | Acceleration due to gravity (m/s²) |
| h | Height above chosen reference level (m) |
| m | Mass (kg) |
When to use this
Near Earth's surface with g approximately constant; h measured from arbitrary datum where U=0 is set.
