Flashcards in Termonology Deck (18):
1

Potential energy (1)

Energy that is stored in several forms.

2

Kinetic energy (2)

Energy in the form of movement, referring to movement of objects and practicals they consist on.

3

Electric energy (1)

Energy made available by flow of a electric current.

4

Electromagnetic energy (3)

Energy that is discharged by magnetic waves. Can move through empty spaces. Comes in many forms, light is the most common.

5

Cell (1)

A device that can convert chemical energy into electric energy.

6

Battery (1)

Two or more cells

7

Atom (1)

Smallest unit of an element.

8

Electrons (1)

Negatively charged parts of an atom.

9

Protons (1)

Positively charged parts of an atom.

10

Static electricity (3)

When charged is placed on a non-conductive metal (insulators) and charge can't pas through. Then the object carries static electricity.

11

Electrical current (1)

Flow of electric charge

12

Ampere (1)

Unit in which electrical current is measured

13

Dynamo/generator (1)

Device used to turn mechanical energy into electrical energy

14

Renewable sources (3)

Source of energy that is replenished through natural processes faster than it is being used. E.g. Wind, sun, biomass

15

Non-renewable sources (1)

Natural resources that cannot be replaced after used

16

Turbine (1)

Device with lots of rotating blades, set to motion using water/wind.

17

Fossilization (3)

A slow process where organic material are turned into stone by high heat and pressure.

18

Photons (1)

Tiny partials of visible light.
