Description: In physics, energy is the quantitative property that must be transferred to a body or physical system to perform work on the body, or to heat it. Energy is a conserved quantity; the law of conservation of energy states that energy can be converted in form, but not created or destroyed.

SI unit: joule

Dimension: M L2 T−2

Other units: kW⋅h, BTU, calorie, eV, erg, foot-pound


The energy equation (Eq. 4.3) represents conservation of energy of a fluid element. The left side represents the rate of change of internal energy of a fluid element. There is a time component and a spatial component because the fluid element under consideration is moving.


1 Joule (J) is the MKS unit of energy, equal to the force of one Newton acting through one meter. 1 Watt is the power from a current of 1 Ampere flowing through 1 Volt. 1 kilowatt is a thousand Watts. 1 kilowatt-hour is the energy of one kilowatt power flowing for one hour.


The definition of quantum from Dictionary.com is “the smallest quantity of radiant energy, equal to Planck’s constant times the frequency of the associated radiation”. This definition is essentially referring to the Planck relation (E=hf) equation that was defined by Max Planck.


Examples of energy stores


Energy store
Elastic potential The energy stored when an object is stretched or squashed.
Gravitational potential The energy of an object at height.
Nuclear The energy stored in the nucleus of an atom.
