===Meaning===
'''Calculating energy stores''' can be done using information about [[Property|properties]], motion and [[Field (Physics)|fields]] affecting an [[object]].

===About Calculating Energy Stores===
The following '''[[Energy Store|energy stores]] can be calculated''' from other quantities:
*'' [[Thermal Energy Store|Thermal Energy]] = Mass x (Specific Heat Capacity) x (Change in Temperature)''
*'' [[Elastic Potential Energy Store|Elastic Potential Energy]] = 0.5 x (Spring Constant) x (Extension)<sup>2</sup>''
*'' [[Kinetic Energy Store|Kinetic Energy]] = 0.5 x (Mass) x (Speed)<sup>2</sup>''
*'' [[Gravitational Potential Energy Store|Gravitational Potential Energy]] = (Mass) x (gravitational field strength) x (change in height)''
