Energy Conversion Cards

Question Answer
the energy stored in a substance that can be released when the substance reacts chemical energy
a method of charging an object that happens when electrons move from one object to another by direct contact conduction – electrical
the transfer of energy from one substance to another through direct contact; can also occur within a substance conduction – thermal
the transfer of energy by the movement of a liquid or gas convection
the energy of moving electrons electrical energy
the ability to do work energy
a change from one form of energy into another; any form of energy can be converted into any other form of energy energy conversion
a force that opposes motion between two surfaces that are touching friction
the energy of motion that depends on speed and mass kinetic energy
states that energy is neither created nor destroyed law of conservation of energy
the sum of an object's kinetic and potential energy mechanical energy
the form of energy associated with changes in the nucleus of an atom nuclear energy
the energy of position or shape potential energy
the transfer of energy through matter or space as waves radiation (radiant energy)
the energy caused by an object's vibrations sound energy
the total energy of the particles that make up an object thermal energy
located between the visible spectrum wavelenghts and X-ray wavelengths ultraviolet light
Machines use this kind of energy to do work. mechanical energy
Radiant energy is also known as electromagnetic energy
When coal is burned to boil water what type of energy conversion is completed? chemical energy to thermal energy
At what point does a roller coaster have the greatest potential energy? at the top of the biggest hill
What kind of energy it stored in a stretched rubber band? Potential energy
In every conversion, some energy is always converted into ___________. thermal energy
Explain the energy conversions that take place while using a hair dryer. electrical to mechanical to kinetic and sound electrical to thermal
Explain the energy conversions that take place when grilling food using wood. chemical to thermal and light
Name some places where chemical energy be stored. food, human body, wood, batteries, coal….
Microwaves use which type of energy to heat your food? Radiant energy (light energy)
Mechanical energy is the sum of all __________ and __________ energy in an object. potential and kinetic
Explain why you can not "lose" energy in terms of the law of conservation of energy. The law of conservation of energy says that energy can not be created nor destroyed but only transferred to something else.
