(physics) The internal energy of a system in thermodynamic equilibrium due to its temperature / (engineering) A form of energy; sensible energy; heat / (military) The energy released by an explosion

Energy contained in a fuel, electricity, or similar carrier of energy derived from some a primary energy source.

(physics) The energy that must be supplied to an initially spherical atomic nucleus to give it a sufficient deformation to undergo nuclear fission according to the Bohr-Wheeler theory

(physics) A property, characteristic of the state of a thermodynamic system, the change of which is equal to the heat absorbed minus the work done by the system.

(physics) Any of the discrete stable energies that a quantum mechanical system (such as the electrons of an atom) can have. / Used other than figuratively or idiomatically: see energy, level.

Energy in an interaction that is not supplied by the initiator of the interaction.

(physics) The energy possessed by an object because of its motion, equal (nonrelativistically) to one half the mass of the body times the square of its speed.

(alternative medicine) The spiritual or etheric energy produced by an individual living being.

(physics) of an elementary particle, or the equivalent electromagnetic radiation, having an energy greater than a hundred thousand electron volts

The energy possessed by an object because of its position (in a gravitational or electric field), or its condition (as a stretched or compressed spring, as a chemical reactant, or by having rest mass).
