A decrease in spring length from its equilibrium position or length.
Elastic Potential Energy
The energy stored in a spring when work is done in compressing or stretching it; a scalar quantity.
Electromagnetic Energy
The energy associated with electric or magnetic fields.
An increase in spring length from its equalibrium length or position.
The ability to do work; a scalar quantity.
Device that converts mechanical energy into and electrical energy by rotating a large coil of wire in a magnetice field.
Gravitational Potential Energy
The work done or the energy change of an object resulting from lifting the oject to a height above Earth's surface; a scalar quantity.
Ideal Mechanical System
A closed system in which no friction or other nonconservative force is acting.
Internal Energy
The total potential and kinetic energy possessed by the particles that made up an object, but excluding the potential and kinetic energy of the system as a whole.
A derived SI unit equal to the work done when a force of one newton produces a displacement of one meter; the unit for electrical energy.
Kinetic Energy
The energy of an object due to its motion; a scalar quantity.
Law of Conservation of Energy
States that in a closed, isolated system, the total charge of the system remains constant.
Mechanical Energy
The sum of the kinetic and potential energies in a system; a scalar quantity.
Device that converts electrical energy into mechanical energy as a result of forces on a current-carrying conductor in a magnetic field.
Nonideal Mechanical System
A system in which a nonconservative force such as friction is acting.
Nuclear Energy
The energy released by nuclear fission, the division of a heavy atomic nucleus into parts of comparable mass, or by nuclear fusion, the combining of two light nuclei to form a heavier nucleus; a scalar quantity.
A device that converts light, a form of electromagnetic radiation, into electrical energy.
Potential Energy
The energy possessed by an object due to its position or condition; a scalar quantity.
The rate at which work is done or energy is consumed; a scalar quantity.
Spring Constant
The constant of proportionality between the applied force and the compression or elongation of a spring.
Thermal Energy
Also called heat; is the total kinetic energy possessed by the individual particles that comprise an object.
The derived SI unit of power equal to on joule per second.
The transfer of energy to an object when the object moves due to the application of a force that is entirely in the direction of motion or has a component in the direction of the object's motion.
