Gravitational Potential Energy vs. Elastic Potential Energy — What's the Difference?

Gravitational Potential Energy and Elastic Potential Energy, both crucial concepts in physics, pivotally define different aspects of energy storage in a system. Gravitational Potential Energy (GPE) derives fundamentally from an object's position in a gravitational field, usually related to its height above a reference point. Contrastingly, Elastic Potential Energy (EPE) is prominently associated with the deformation of an object, such as the compression or elongation of a spring, which fundamentally diverges from the positional basis of GPE.

In practical applications, Gravitational Potential Energy plays a key role in scenarios involving altitude changes, like a ball rolling down a hill, showcasing its dependency on mass, gravitational acceleration, and height. Conversely, Elastic Potential Energy finds its niche in scenarios involving elastic deformation, such as an archer pulling back a bowstring, indicating a stark divergence from GPE by its reliance on deformation and intrinsic object properties like spring constant.

Considering energy transformation, Gravitational Potential Energy readily converts to kinetic energy as an object falls, highlighting a straightforward conversion mechanism tied to positional change. Elastic Potential Energy, meanwhile, transforms into kinetic energy as a deformed object returns to its original shape, illustrating its conversion mechanism as intrinsically tied to deformative restoration rather than positional alteration as seen with GPE.

Regarding dependencies, Gravitational Potential Energy largely hinges on external factors like gravitational field strength and relative height. Elastic Potential Energy, however, is primarily dependent on intrinsic object properties and the extent of deformation, portraying a divergence in dependency on external vs. internal factors between GPE and EPE respectively.
