Advanced Potential Energy Calculator – Metric & Imperial

Use this free online Potential Energy Calculator to calculate the gravitational potential energy of an object, or reverse solve for mass or height based on the well-known physics formula:

PE = m × g × h

Key Features:

  • Switch between Metric (kg, m) and Imperial (lb, ft) units
  • Calculate Potential Energy, or reverse solve for Mass or Height
  • Supports custom gravity values (e.g., Earth, Moon, Jupiter)
  • Live animated formula updates based on inputs
  • Visual diagram of object height and gravity effect

What is Potential Energy?

Potential energy is the energy stored by an object due to its position in a gravitational field. The higher the object and the greater its mass, the more potential energy it has. The formula is:

PE = m × g × h
where:
PE = Potential Energy (Joules)
m = Mass (kg or lb)
g = Gravity (default 9.81 m/s² or 32.17 ft/s²)
h = Height (m or ft)

Examples of Use:

  • Physics students calculating energy of a falling object
  • Engineering applications requiring gravitational energy estimates
  • Compare how PE changes on the Moon vs. Earth

Diagram Explanation:

The visual diagram (or animation above the calculator) helps you understand the relationship between height, mass, and gravity. As the object gains elevation, it gains energy potential, ready to convert into kinetic energy when released.

Calculator FAQ:

  • Can I change gravity? Yes, the default is 9.81 m/s², but you can input custom values for other planets or scenarios.
  • Can I use feet and pounds? Yes, switch the unit system to “Imperial” to use ft and lb.
  • Can I calculate in reverse? Yes, you can choose to solve for mass or height instead of potential energy.
