Where Is Zero Potential Energy?

The zero level is a chosen reference. Height in this worksheet is measured relative to that reference.

Is Gravity Constant Everywhere?

No. The presets are useful averages; precise work needs location- and altitude-specific data.

Solve gravitational potential energy, mass or height with selectable local gravity.

The Potential Energy Calculator resolves PE = mgh for energy, mass or height and keeps the local gravitational acceleration visible.

Choose the unknown, enter the other measurements and select Earth, Moon, Mars or Jupiter gravity when appropriate.

Use it for near-surface mechanics calculations where gravity can be treated as uniform over the height change.

Where Is Zero Potential Energy?: The zero level is a chosen reference. Height in this worksheet is measured relative to that reference.
Is Gravity Constant Everywhere?: No. The presets are useful averages; precise work needs location- and altitude-specific data.
