The Gravitational Potential Energy calculator computes the potential energy (PE) of a body with a certain mass (m) at rest at a certain height (y).
INSTRUCTIONS: Choose the preferred units and enter the following:
Potential Energy (PEgrav): The calculator returns the potential energy in Joules (J). However this can be automatically converted to other energy units via the pull-down menu.
If we usewhere a is the acceleration due to gravity (g)
Therefore we get this formula:
Where the inputs are, mass (m) and vertical displacement (y). The default units for Potential Energy are Joules (J) for potential energy, meters per second (m/s²) for , and meters (m) for vertical displacement.
The defaultis that of surface of the Earth at Sea Level (9.80665 m/s² ) . The user can override the default with other values.
