How the Potential Energy Formula Works
Gravitational potential energy is stored energy caused by position in a gravity field. Near a planet's surface, the formula is:
Where m is mass in kilograms, g is gravity in meters per second squared, and h is height in meters. The result is in joules (J). Double any one of these values and potential energy doubles too.
This tool also rearranges the same formula when needed: m = PE / (g Ć h) and h = PE / (m Ć g). Inputs in pounds, feet, watt-hours, and other units are converted to SI units internally for consistent math, then displayed back in the unit you selected.
This model assumes constant gravity and ignores air resistance, friction, and system losses. It is ideal for education and rough planning. For critical engineering decisions, validate with full system calculations.
About This Tool
This potential energy calculator is for students, educators, and engineers who need fast and trustworthy gravitational energy checks. Instead of manually rearranging formulas and converting units, you can switch between finding energy, mass, or height in one place and test scenarios in seconds.
The interactive sliders let you explore how changing mass or height affects energy in real time. Planet gravity cards make it easy to compare energy stored on Earth vs. the Moon, Mars, or Jupiter.
