Gravitational vs Elastic Potential Energy

What is the main difference between gravitational and elastic potential energy?

• Gravitational potential energy is related to an object's position in a gravitational field, while elastic potential energy is related to the deformation of an elastic object.

• Gravitational potential energy is a vector quantity, while elastic potential energy is a scalar quantity.

• Gravitational potential energy is constant, while elastic potential energy varies with temperature.

• Gravitational potential energy is related to sound waves, while elastic potential energy is related to light waves.
