Types of Energy

Question 1

potential energy

Answer 1

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

Question 2

Kinetic energy

Answer 2

energy due to the motion of an object

Question 3

Gravitational energy

Answer 3

The potential energy of an object off the ground

Question 4

Elastic energy

Answer 4

Energy stored in a elastic object that is stretched

Question 5

Chemical energy

Answer 5

Energy made from chemicals

Question 6

Nuclear energy

Answer 6

Energy stored in the nucleus of atoms

Question 7

Electrical energy

Answer 7

Energy made from electrical currents

Question 8

Heat energy

Answer 8

The energy that causes an object to gain temperature

Question 9

Light energy

Answer 9

Energy from an object radiating light

Question 10

Sound energy

Answer 10

Energy passing by sound vubrations

Question 11

conduction

Answer 11

transfer of heat through collisions between particles

Question 12

insulators

Answer 12

a material that is a poor conductor of heat

Question 13

convection

Answer 13

transfer of heat through the flow of particles

Question 14

radiant heat

Answer 14

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

Question 15

Reflected

Answer 15

To bounce off something

Question 16

transmitted

Answer 16

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

Question 17

absorbed

Answer 17

To take in

Question 18

deciduous

Answer 18

describes plants that lose their leaves during autumn and winter

Question 19

luminous

Answer 19

releasing its own light

Question 20

incandescent

Answer 20

describes objects that emit light when they are hot

Question 21

bioluminescent

Answer 21

describes living things that release light energy

Question 22

non-luminous

Answer 22

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

Question 23

electromagnetic radiation

Answer 23

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

Question 24

electromagnetic spectrum:

Answer 24

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

Question 25

radio waves

Answer 25

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

Question 26

infra-red radiation

Answer 26

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

Question 27

ultraviolet radiation

Answer 27

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

Question 28

X-rays

Answer 28

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

Question 29

gamma rays

Answer 29

high energy electromagnetic radiation produced during a nuclear reaction

Question 30

vibrations

Answer 30

repeated fast, back-and-forth movements

Question 31

compression

Answer 31

the process of pushing a material into itself
