Flashcards in energy Deck (48):
1

potential energy

stored energy that, when released, is converted to other forms such as kinetic, sound, heat or light energy.

2

kinetic energy

energy relocated by objects that are moving.

3

types of energy

nuclear, elastic, electric, light, heat, sound and gravitational.

4

conduction

heat transfer through collisions of particles.

5

insulators

a weak conductor of heat.

6

convection

a flow of heat changing through particles.

7

radiation

an energy force of heat that does not require any transfer.

8

radiant heat

a radiated heat from the sun.

9

reflected

redirect off.

10

transmitted

come through.

11

absorbed

energy take in.

12

chemical energy

chemical energy is also the source of the heat produced.

13

movement energy

the kinetic energy of an object is the energy that it possesses due to its motion.

14

mechanical energy

mechanical energy is the sum of potential energy and kinetic energy.

15

thermal energy

thermal energy refers to the internal energy present in a system due to its temperature

16

Law of Conservation of Energy

It implies that energy can neither be created nor destroyed.

17

electrical energy

Electrical energy is defined as an electric charge that lets work be accomplished.

18

elastic energy

an amount of energy that can be stored which can be rebound.

19

gravitational energy

it is energy associated with gravity or gravitational force.

20

light energy

Light energy is the only form of energy that we can actually see directly.

21

heat energy

Thermal energy is an example of kinetic energy, as it is due to the motion of particles.

22

sound energy

Sound energy is produced when an object vibrates. The sound vibrations cause waves of pressure that travel through a medium, such as air, water, wood or metal.

23

efficiency

quality of being efficient.

24

rotational energy

The work-energy principle is a general principle which can be applied specifically to rotating objects.

25

luminous

Something that is luminous shines or glows in the dark.

26

incandescent

Incandescent substances or devices give out a lot of light when heated.

27

bioluminescent

the production of light by living organisms.

28

non-luminous

Something that isn't luminous shines or glows in the dark.

29

scattered

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

30

visible spectrum

the range of wavelengths of electromagnetic radiation that is normally visible, from 380 to 760 nm.

31

dispersion

the variation of the index of refraction of a transparent substance, as glass, with the wavelength of light, with the index of refraction increasing as the wavelength decreases.

32

electromagnetic radiation

radiation consisting of electromagnetic waves, including radio waves, infrared, visible light, ultraviolet, x-rays, and gamma rays.

33

electromagnetic spectrum

radiation consisting of electromagnetic waves, including radio waves, infrared, visible light, ultraviolet, x-rays, and gamma rays.

34

radio waves

an electromagnetic wave having a wavelength between 1 millimetre and 30,000 meters, or a frequency between 10 kilohertz and 300,000 megahertz.

35

infra-red radiation

The light we see with our eyes is really very small.

36

ultraviolet radiation

Radiation in the part of the electromagnetic spectrum where wavelengths are just shorter than those of ordinary, visible violet light but longer than those of x-rays.

37

X-rays

Often, x-rays. a form of electromagnetic radiation, similar to light but of shorter wavelength

38

gamma rays

a photon of moving through electromagnetic radiation

39

vibrations

the state of being vibrated.

40

rarefactions

the act or process of rarefying

41

compression

the effect, result, or consequence of being compressed.

42

sound waves

wave in an elastic medium, especially a wave producing an audible sensation.

43

frequency

Also, a frequency of state or fact of being frequent; frequent occurrence.

44

hertz

the standard unit of frequency in the International System of Units

45

pitch

the highness or lowness of a sound. The pitch that you hear depends on the frequency of the vibrating air.

46

wavelength

the distance, measured in the direction of propagation of a wave, between two successive points in the wave that are characterized by the same phase of oscillation.

47

amplitude

the state or quality of being ample, especially as to breadth or width; largeness; greatness of extent.

48

reverberation

the persistence of a sound after its source has stopped, caused by multiple reflections of the sound within a closed space.
