Frequently Asked Questions
What is gravitational potential energy?
Gravitational potential energy (GPE) is the energy stored in an object due to its position in a gravitational field. It represents the work done against gravity to lift an object to a certain height and is calculated using the formula PE = mgh.
How do you calculate gravitational potential energy?
Gravitational potential energy is calculated using the formula PE = mgh, where PE is potential energy (in joules), m is mass (in kg), g is gravitational acceleration (9.81 m/s² on Earth), and h is height (in meters) above the reference point.
What units are used for gravitational potential energy?
Gravitational potential energy is measured in joules (J) in the SI system. Other common units include kilojoules (kJ), megajoules (MJ), calories (cal), kilocalories (kcal), and foot-pounds (ft·lbf). Our calculator supports all these units with automatic conversion.
What is the value of gravitational acceleration on Earth?
The standard gravitational acceleration on Earth is 9.81 m/s² (or 9.80665 m/s² precisely). This value varies slightly with altitude and latitude, being 9.780 m/s² at the equator and 9.832 m/s² at the poles due to Earth's rotation and shape.
Can I calculate other variables besides potential energy?
Yes, our calculator can solve for any variable in the PE = mgh equation. You can calculate potential energy, mass, gravitational acceleration, or height when the other three values are known. Simply select what you want to calculate from the dropdown menu.
Is this gravitational potential energy calculator free?
Yes, our gravitational potential energy calculator is completely free to use. There are no limits on calculations, no registration required, and all features including unit conversions and detailed results are available at no cost.
