1. Energy Conversion and Types of Energy
Energy can be classified into six general forms: chemical, mechanical, thermal, light, electrical and nuclear.
Chemical energy is potential energy ____________in chemical substances. Gasoline, for instance, has a large amount of stored chemical energy. This energy can be used to power a ________.
Mechanical energy is the energy ____________ or ____________ by a moving object. Mechanical energy propels a baseball after it has been struck by a bat.
Thermal energy is associated with the motion of molecules. It is a type of energy that usually results from the friction caused by molecules rubbing against one another. Thermal energy is produced when: _______________________________.

2. Light energy is a form of electromagnetic energy
Light energy is a form of electromagnetic energy. Each color of light represents a different amount of electromagnetic energy. Electromagnetic energy also includes: _______________________________
Electrical energy is associated with the movement of electrons. Devices such as ___________________ are operated by this form of energy.
Nuclear energy is energy __________ in the nucleus of an atom. When a nucleus splits, nuclear energy is released (fission). Nuclear energy is also released when the nuclei of atoms fuse together (fusion).
 Any one of the six forms of energy can be ____________ into another form. For example, plants capture light energy from the sun and convert it to chemical energy during the process of photosynthesis. Often a series of energy conversions is needed to do a job. For example, wind turns a wind turbine to produce mechanical energy, which activates an electrical generator to produce electricity for a radio.
