GRAVITATIONAL POTENTIAL ENERGY
The energy stored in an object due to its height or distance above the ground

Gravitational potential energy depends on the mass of an object and the height of an object.

ELASTIC POTENTIAL ENERGY
The energy stored in an object due to a change in its usual position

Elastic potential energy depends on how much an object is changed from its regular position.

KINETIC ENERGY
The energy of an object in motion

Objects can have neither potential energy or kinetic energy.

CONCLUSION
Potential and Kinetic
Two kinds of potential energy
They both depend on certain factors
Objects can have both, can have neither
