What Is Energy? Energy Definition and Examples (Science)
https://sciencenotes.org/energy-definition-examples/
The term “energy” comes from the Greek word energeia or from the French words enmeaning in and ergon which means work. The SI unit of energy is the joule (J), where 1 J = 1kg⋅m2⋅s−2. Other units include the kilowatt-hour (kW-h), British thermal unit (BTU), calorie (c), kilocalorie (C…

In the International System of Units (the SI system), the unit of energy is the joule. The specific heat capacity (or just specific heat) of a material is defined as the amount of heat required to raise the temperature of one gram (g) of the material one degree Celsius (ºC). It takes 4.18 joules (J) to raise the temperature of 1 g of water 1ºC (at ...

energy, in physics, the capacity for doing work. It may exist in potential, kinetic, thermal, electrical, chemical, nuclear, or other various forms. There are, moreover, heat and work—i.e., energy in the process of transfer from one body to another. After it has been transferred, energy is always designated according to its nature.
