Forms of Energy

Kinetic Energy
The energy of motion.

Potential Energy
Energy difference between the energy of an object in a given position and its energy at a reference position.

Mechanical
The energy that is possessed by an object due to its motion or due to its position.

Electrical
The energy that is possessed by an object due to its motion or due to its position.

Light/Radiant
The energy of electromagnetic and gravitational radiation.

Sound
A type of kinetic energy that is made from the vibration of matter.

Thermal
The energy contained within a system that is responsible for its temperature.

Chemical
Is released when bonds form in a chemical reaction, often producing heat as a by-product

Gravitational
Potential energy a body with mass has in relation to another massive object due to gravity.

Nuclear
The energy released by a nuclear reaction, especially by fission or fusion.

Radiation
Occurs when heat travels through empty space.

Conduction
The heat transfer from the hotter part to the colder one.

th (3) Convection
The heat transfer by up and down motion of the fluid.

Nucleus

Fission
A nuclear reaction or a radioactive decay process in which the nucleus of an atom splits into smaller, lighter nuclei.

Fusion
A nuclear reaction in which atomic nuclei of low atomic number fuse to form a heavier nucleus with the release of energy.

Elastic
Stored in the configuration of a material or physical system as work is performed to distort its volume or shape.

Energy Laws

Law of Conservation of Energy
A physical law that states energy cannot be created or destroyed but may be changed from one form to another.

Law of Conservation of Matter/Mass
The mass of substances in a closed system will remain constant

Gas Laws

Boyle's Law
The pressure of a given mass of an ideal gas is inversely proportional to its volume at a constant temperature.

Charles' Law
The volume of an ideal gas at constant pressure is directly proportional to the absolute temperature.

Avogadro's Law
The same temperature and pressure, equal volumes of all gases contain the same number of molecules.

Gay-Lussac's Law
The volumes of gases undergoing a reaction at constant pressure and temperature are in a simple ratio to each other and to that of the product.



Combined Law
Combines the three gas laws: Boyle's Law, Charles' Law, and Gay-Lussac's Law and states that the ratio of the product of pressure and volume and the absolute temperature of a gas is equal to a constant. When Avogadro's law is added to the combined gas law, the ideal gas law results.

P1/T1 = P2/T2

V1/T1 = V2/T2

P1V1 = P2V2

V1/n1 = V2/n2

P1V1/T1 = P2V2/T2

Ohm's Law
Electric current is proportional to voltage and inversely proportional to resistance.

Newton's Law
Every object in a state of uniform motion will remain in that state of motion unless an external force acts on it. Force equals mass times acceleration [ ]. For every action there is an equal and opposite reaction.

Direct Current
An electric current flowing in one direction only.

Alternating Current
An electric current that reverses its direction many times a second at regular intervals, typically used in power supplies.
