Unit 5 Forms Of Energy

Front 1

Energy

Back 1

is the ability to cause changes in matter; Can not be created or destroyed; the ability to cause motion or create change.

Front 2

Kinetic energy

Back 2

The energy an object has because its in motion.

Front 3

Potential energy

Back 3

The energy an object has because of it position or condition

Front 4

Chemical energy

Back 4

is energy that is stored in matter and that can be released by a chemical reaction. Example - Energy in food to move and stay warm.

Front 5

Light energy

Back 5

is a form of energy that can travel through space. A form of energy you can see.

Front 6

Electrical energy

Back 6

is energy caused by the movement of electric current.

Front 7

Mechanical energy

Back 7

is the total energy of motion and position of an object. Example Winding the key on the toy increases the toy's energy or the gears in a watch that make the hands move.

Front 8

Sound Energy

Back 8

is energy that travels as waves through vibrating matter.

Front 9

Thermal energy

Back 9

is the total kinetic energy of the particles in matter. (how fast the particles move)

Front 10

transformation

Back 10

Energy can change from one form to another.

Front 11

Kinetic and Potential energy

Back 11

categories of energy

Front 12

vibrate

Back 12

to mover back and forth

Front 13

temperature

Back 13

is a measure of the average kinetic energy of the particles in a substance.

Front 14

Conduction

Back 14

is the transfer of energy between particles that are in contact. Heat flows from the hot item to the cold item.

Front 15

Convection energy

Back 15

is the transfer of energy by currents in a liquid or gas.

Front 16

Radiation energy

Back 16

is the transfer of energy in waves without matter to carry it. Example: Heat from a fireplace.

Front 17

Solar Radiation

Back 17

is the most important energy source on Earth. Only a tiny fraction of this energy reaches Earth.

Front 18

Combustion of fuels

Back 18

is the second most important source of energy on Earth.

Front 19

Geothermal energy

Back 19

is thermal energy naturally produced under Earth's surface. Example: volcanoes, geysers, and hot springs

Front 20

Heat energy

Back 20

is the transfer of energy between substances at different temperatures

Front 21

Electric Charge

Back 21

is a property of a particle that affects how it behaves around other particles. (positive and negative charges)

Front 22

Static electricity

Back 22

Electric charges that build up on an objects.

Front 23

Atoms

Back 23

are the building blocks of all matter; are so small they cannot be seen without a special microscope; they are made up of protons, neutrons, and electrons.

Front 24

Electric Current

Back 24

The flow of electric charges along a path.

Front 25

Repel

Back 25

Two positive charges ____________________ each other.

Front 26

Attract

Back 26

A positive charge and a negative charge __________________ each other.

Front 27

Proton

Back 27

A ____________ has a positive charge.

Front 28

Neutron

Back 28

A _________________ is neutral because it has no charge

Front 29

Electron

Back 29

An __________________ has a negative charge.

Front 30

Station

Back 30

Electricity is produced at a generating ______________.

Front 31

Conductor

Back 31

Allows electricity to easily travel through them. (example: Copper Wire)

Front 32

insulator

Back 32

Prevents the flow of electricity. (Example: Rubber Gloves)

Front 33

circuit

Back 33

A complete pathway made of conductors through which electric current can flow.

Front 34

series circuit

Back 34

Electric current has only one path to follow to and from the energy source. (example: Christmas lights that if one light bulb goes out they all go out)

Front 35

parallel circuit

Back 35

contains two or more paths for electric charges to follow. (example: Each light has its own path for electricity to flow)
