About the Potential Energy Calculator
Calculate near-surface gravitational potential energy from mass, vertical height change, and local gravitational acceleration.
How the Potential Energy Calculator Works
Mass, signed vertical displacement, and entered local gravity are multiplied to report potential-energy change relative to the chosen zero height.
Formula
Gravitational potential-energy change = mass x gravitational acceleration x height change.

Accuracy and Limitations
The constant-gravity approximation is appropriate only when height is small relative to the attracting body. The result depends on the selected reference height.
Keep units consistent, use measurements that represent the actual situation, retain full precision during the calculation, and round only the final answer. Professional decisions may require current official rules, field measurements, laboratory methods, or specialist review.
