Energy
Electrical energy: electricity; energy due to the flow of electric current through a conductor
Energy: Ability to do work; a matter contains energy according to its motion and position due to a force
Kinetic energy: energy determined by the velocity and the mass of the object in motion
Thermal energy: heat; energy in form of heat due to kinetic energy or potential energy such as kinetic energy of atoms in chemical reaction, for example.
Work: A measure of energy transferred to an object by a constant force

Spring
Hooke's law: "the magnitude of the force exerted by a spring is directly proportional to the distance the spring has moved from equilibrium" (Hirsch, 2003, p. 204)
