Front 10

Kinetic Energy

Back 10

The energy of motion.

Front 11

Potential Energy

Back 11

Stored energy; the energy an object has due
to its position, molecular arrangment, or
chemical composition

Front 12

Law of Conservation of Energy

Back 12

A law stating that no matter how energy is
transferred or transformed, it continues to
exist in one form or another

Front 13

Heat

Back 13

The flow of energy from an object at a higher temperature to a lower temperature.

Front 14

Thermal Energy

Back 14

The energy an object has due to the motion
of its particles.

Front 15

Calorie

Back 15

The amount needed to increase the temperature of one gram of water by one
degree Celsius.

Front 16

Joule

Back 16

A unit used to measure energy and work.

Front 17

Specific Heat

Back 17

The amount of energy required to raise the temperature of one gram of a substance by one degree Celsius.

Front 18

Conduction

Back 18

The process by which energy is transferred from a warmer object to a cooler object by means of physical contact.

Front 19

Conductor

Back 19

A material that transfers energy easily.

Front 20

Insulator

Back 20

A material that does not transfer energy easily.

Front 21

Convection

Back 21

A process by which energy is transferred in gases and liquids, occurring when a warmer, less dense area of gas or liquid is pushed up by a cooler, more dense area of the gas or liquid.

Front 22

Radiation

Back 22

Energy that travels across distances in the form of electromagnetic waves.

Front 23

Resistor

Back 24

An electrical device that slows the flow of charge in a circuit.

Front 25

Short Circuit

Back 25

An unintended and undesired path connecting one part of a circuit with another.

Front 26

Series Circuit

Back 26

A circuit in which current follows a single path.

Front 27

Electric Current that reverses direction at regular intervals.

Front 35

Transformer

Back 35

A device that uses electromagnetism to increase or decrease voltage.
