energy
the strength and vitality required for sustained physical or mental activity.
work
the transfer of energy to an object by a force that causes the object to move in the direction of that force
kinetic energy
energy of motion
potential energy
an object that has stored energy based on its relative position within a system or its condition
mechanical energy
the sum of potential and kinetic energy
thermal energy
internal energy of an object due to the kinetic energy of its atoms and/or molecules
electromagnetic energy
form of energy that is reflected or emitted from objects in the form of electrical and magnetic waves that can travel through space
sound energy
form of energy associated with the vibration of matter
electrical energy
he energy newly derived from electric potential energy or kinetic energy.
elastic energy
is the potential mechanical energy stored in the configuration of a material or physical system as work is performed to distort its volume or shape
chemical energy
is the potential of a chemical substance to undergo a transformation through a chemical reaction to transform other chemical substances
nuclear energy
the energy released during nuclear fission or fusion, especially when used to generate electricity.
