Types of energy By john henry gadson 1st period science –6th grade
Kinetic enrgy the kinetic energy of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes.
Elecricenrgy • the energy newly derived from electric potential energy or kinetic energy. When loosely used to describe energy absorbed or delivered by an electrical circuit (for example, one provided by an electric power utility) "electrical energy" talks about energy which has been converted from electric potential energy.
Potential energy • potential energy is the energy that an object has due to its position in a force field or that a system has due to the configuration of its parts.
Chemical energy • chemical energy is the potential of a chemical substance to undergo a transformation through a chemical reaction to transform other chemical substances. Examples include batteries, food, gasoline, and more. Breaking or making of chemical bonds involves energy, which may be either absorbed or evolved from a chemical system.
Nuclear energy Nuclear power is the use of nuclear reactions that release nuclear energy to generate heat, which most frequently is then used in steam turbines to produce electricity in a nuclear power plant. The term includes nuclear fission, nuclear decay and nuclear fusion.
Gravitational energy • Gravitational energy is potential energy associated with the gravitational field. This phrase is found frequently in scientific writings about quasars (quasi-stellar objects) and other active galaxies. Quasars generate and emit their energy from a very small region.
Mechanical energy mechanical energy is the sum of potential energy and kinetic energy. It is the energy associated with the motion and position of an object. The law of conservation of mechanical energy states that in an isolated system that is only subject to conservative forces the mechanical energy is constant.
Thermal energy thermal energy refers to the internal energy present in a system due to its temperature. The average translational kinetic energy possessed by free particles in a system of free particles in thermodynamic equilibrium (as measured in the frame of reference of the center of mass of that system) may also be referred to as the thermal energy per particle.
Sound energy • is the energy produced by vibrating sound waves. Facts About Sound Energy Sound energy moves through a process of vibrating air molecules, which create a chain reaction of vibrating molecules that the ear perceives as sound.
Seismic energy • the vibration of the ground due to the release of elastic energy from the breakage of rock within the earth or an explosion. The phenomenon is commonly referred to as an earthquake, but while seismic waves can be either body waves or surface waves, an earthquake radiates seismicenergy as both types of waves.
Radiant energy • the energy of electromagnetic and gravitational radiation. The SI unit of radiant energy is the joule (J). The quantity of radiant energy may be calculated by integrating radiant flux (or power) with respect to time. The symbol Qe is often used throughout literature to denote radiant energy ("e" for "energetic", to avoid confusion with photometric quantities).
Solar energy • Solar energy can be broken down into two categories; solar electric and solar thermal. Solar electric consists of photovoltaics (PV) and concentrated solar power (CSP) that produces electricity. Solar thermal technologies capture the sun's thermal energy for water or space heating.
