Flashcards in Energy Deck (30):
1

Potential Energy

Energy that has the potential to do work.

2

Kinetic Energy

Energy that is quickly transformed into movement.

3

Nuclear

relating to the nucleus of an atom.

4

Mechanical

the motion of large objects

5

Thermal

relating to heat.

6

Movement

an act of moving.

7

Chemical

a distinct compound or substance, especially one which has been artificially prepared or purified.

8

Electric

of, worked by, charged with, or producing electricity.

9

Light

the natural agent that stimulates sight and makes things visible.

10

Sound

vibrations that travel through the air or another medium and can be heard when they reach a person's or animal's ear.

11

Gravitational

relating to movement towards a centre of gravity.

12

Law of Conservation of Energy

a law that states that energy cannot be made or lost. However, energy can be transformed from one type to another or transferred from one object to another.

13

Electrical Energy

used to move charged particles through a wire from a power plant to our homes and businesses. The movement of a charged particle through a wire is called current, or more commonly, electricity.

14

Gravitational Potential Energy

energy an object possesses because of its position in a gravitational field.

15

Elastic Potential Energy

Elastic potential energy is Potential energy stored as a result of deformation of an elastic object, such as the stretching of a spring. It is equal to the work done to stretch the spring, which depends upon the spring constant k as well as the distance stretched.

16

Efficiency

a measure of how much work or energy is conserved in a process.

17

Convection

the movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity, which consequently results in transfer of heat.

18

Conduction

the process by which heat or electricity is directly transmitted through the material of a substance when there is a difference of temperature or of electrical potential between adjoining regions, without movement of the material.
-the process by which sound waves travel through a
-medium.
-the transmission of impulses along nerves.

19

Radiation

The emission of energy as electromagnetic waves or as moving subatomic particles, especially high-energy particles which cause ionization.

20

Density

the degree of compactness of a substance.

21

Deciduous

Describes plants that lose their leaves during autumn and winter

22

Insulators

A Material that is a Poor Conductor of heat.

23

Radiant Heat

Heat transferred from the Sun to the Earth.

24

Reflected

Bounced off.

25

Transmitted

Passing through something such as Light or Sound passing through the air.

26

Absorbed

Taken in.

27

Luminous

Something that releases its own light.

28

Incandescent

Describes objects that emit light when they are hot.

29

Scattered

Describes light sent in many directions.

30

Dispersion

Separation of the colours that make up White Light.
