Flashcards in Energy Deck (33):
1

Kinetic energy

Energy due to the motion of an object

2

Potential energy

Energy that has the potential to do work and so the energy is ‘stored’, such as gravitational energy, elastic energy and chemical energy

3

Conduction

Transfer of heat through collisions between particles

4

Insulators

A material that is a poor conductor of heat

5

Conduction

Transfer of heat through collisions between particles

6

Insulators

A material that is a poor conductor of heat

7

Convection

Transfer of heat through the flow of particles

8

Radiation

A method of heat transfer that does not require particles to transfer heat from one place to another

9

Radiant heat

Heat transferred by radiation, as from the sun to the Earth

10

Reflected

Bounced off

11

Transmitted

Passed through something, such as light or sound passing through air

12

Absorbed

Taken in

13

Deciduous

Describes plants that lose their leaves during autumn and winter

14

Conductor

A material or device that conducts or transmits heat or electricity, especially when regarded in terms of its capacity to do this.

15

Insulator

A substance which does not readily allow the passage of heat or sound.

16

Luminous

Releasing its own light

17

Incandescent

Describes objects that emit light when they are hot

18

Bioluminescent

Describes living things that release light energy

19

Non-luminous

Describes objects that do not emit their own light, but can be seen by reflected light

20

Scattered

Describes light sent in many directions by small particles within a substance

21

Visible spectrum

Different colours that combine to make up white light; they are separated in rainbows

22

Dispersion

Separation of the colours that make up white light. Each colour is bent differently when it enters or leaves a glass prism.

23

Electromagnetic radiation

The radiant energy such as radio waves, infrared, visible light, X-rays and gamma rays released by magnetic or electric fields

24

Electromagnetic spectrum

Complete range of wavelengths of energy radiated as electric and magnetic fields

25

Radio waves


Low energy electromagnetic waves with a much lower frequency and longer wavelength than visible light

26

Infra-red radiation

Low energy electromagnetic waves with a much lower frequency and longer wavelength than visible light

27

Ultraviolet radiation

Invisible radiation similar to light but with a slightly higher frequency and more energy

28

X-rays

High energy electromagnetic waves that can be transmitted through solids and provide information about their structure

29

Gamma rays

High energy electromagnetic radiation produced during nuclear reaction

30

Vibrations

Repeated fast, back-and-forth movements

31

Compression

The process of pushing a material into itself

32

Rarefactions

In sound waves, the layers of air particles that are spread apart (between compressions)

33

Sound waves

Vibrations of particles in the air
