E
A property of matter that can be transferred from one form into another form for the purpose of doing work.
Energy
Energy related to an objects height.
Gravitational Potential Energ
A form of potential energy associated with atoms. The energy is stored inside the nucleus. There are two types of reactions that cause this energy to be released.
Nuclear Energy
A characteristic of a substance that can be observed without changing the substance in different substances. EXAMPLES: Solids, Liquids, Color, Hardness, Texture, Shine, Luster; ability to dissolve in water and conduct electricity.
Physical Properties
Type of machine that converts electrical energy into mechanical energy.
Motor
A change in one form of energy into another form.
Energy Transformation
A form of energy associated with the position and motion of an object. Mechanical energy is the total energy found in an object. This energy is equal to the sum of an object's potential and kinetic energies. The more mechanical energy an object has the more work it can do.
Mechanical Energy
A nuclear reaction where the nuclei of atoms fuse or bond together. This reaction occurs on stars and our sun.
Fusion
During a chemical reaction or phase change, the temperature of the surroundings increase. A reaction that gives off heat and warms its surroundings. Chemical compounds are either endothermic or exothermic. EXOTHERMIC EXAMPLES: Burning flame, rusting iron, nuclear fission, formation of snow in clouds.
Exothermic Process
A machine that converts mechanical energy into electrical energy
Generator
Stored energy that as a result of its position or shape has the ability to perform work or create motion. This energy has the "potential" to perform work.
Potential Energy
A form of energy associated with the atoms and molecules of an object. This energy is equal to the sum of the total potential and kinetic energies found in the small particles of an object. Can be measured by temperature.
Thermal Energy
This form of energy travels in waves. The waves have magnetic and electrical properties. Forms are: radio, microwave, infrared, visible, ultraviolet, X-rays and gamma rays
Electromagnetic Energy
Coal, oil and natural gas are examples. Accumulated ancient remains of plants and animals that were deposited millions of years ago. Humans burn fossil fuels directly and indirectly to generate energy.
Fossil Fuel
Measurement of hot or cold. Thermometer measures a substance's average kinetic energy (Remember: atoms in motion have more kinetic energy and produce more heat)
Temperature
Comes from greek word kinetos meaning "motion" The energy that an object has as a result of its motion. The moving object has the ability to perform work. This energy is the "energy" of motion.
Kinetic Energy
A form of energy associated with the atoms or molecules of an object. It is a form of potential energy. This energy moves along wires and particles transfer from one position to another position along the circuit. When this energy is put to use it converts into another type of energy.
Electrical Energy
In a closed system, matter can change form but cannot be created or destroyed.
Law of Conservation of Matter
The process of burning fuel to create thermal energy. Example of a type of chemical change.
Combustion
Known as phases of matter: solid, liquid, gas and plasma.
States of Matter
Materials that can be stretched or compressed are said to have this type of potential energy. Examples: a bow and arrow and rubber band. The bow stores the energy until it is released.
Elastic Potential Energy
A form of potential energy associated with the atoms or molecules of an object. This energy is released when the bonds between atoms and molecules are broken. Food or when materials burn are good examples.
Chemical Energy
In a closed system, energy can change form and remains constant. The energy in the system is constant.
Law of Conservation of Energy
Type of machine that uses thermal energy to create mechanical energy that eventually. The mechanical energy is used to create electricity.
Turbine
The rate at which energy is transferred over a given period of time.
Power
