DANIELA.9) FORMS OF ENERGY.
LIGHT ENERGY
LIGHT ILLUMINATES OBJECTS AND ALLOWS US TO SEE SHAPES, COLOURS AND SIZES.
LIGHT ALWAYS TRAVELS IN A STRAIGHT LINE UNTIL SOMETHING GETS IN ITS WAY.
EVEN THOUG LIGHT LOOKS WHITE, IT´S MADE UP OF SEVEN DIFFERENT COLOURS.
WHEN THAT HAPPENS, LIGHT CAN BE ABSORBED, REFLECTED OR REFRACTED, DEPENDING ON WHAT KIND OF SURFACE IT HITS
LIGHT TRAVELS VERY FAST, IT TRAVELS AT 300.000 KILOMETRES PER SECOND,
LIGHT SOURCES CAN BE NATURAL , SUCH AS THE STARS, OR ARTIFICAL, SUCH AS LIGH BULBS AND TORCHES.
↔
WHEN LIGHT IS ABSORBED, IT TRANSFORMS INTO THERMAL ENERGY.
CHEMICAL ENERGY
CHEMICAL ENERGY IS RELEASED WHEN A CHEMICAL REACTION OCCURS.
BATTERIES AND FOOD ARE SOURCES OF CHEMICAL ENERGY TOO.
↔
KINETIC ENERGY
THE HEAVIER AN OBJECTS IS, AND THE FASTER IT MOVES, THE MORE KINETIC ENEERGY IT HAS.
EXAMPLES OF KINETIC ENERGY ARE MOST TRANSPORTATION
MOVING. LIVING THINGS HAVE KINETIC ENERGY TOO.
KINETIC ENERGY IS PRODUCED HROUGH MOTION OR MOVEMENT.
ELECTRICAL ENERGY
IT IS ALSO PRODUCED IN NUCLEAR POWER STATIONS.
THE ENERGY TO GENERATE ELECTRICITY COMES FROM DIFFERNT SOURCES
.
ELECTRICITY CAN ALSO BE GENERATED USING ENERGY FROM SUNLIGHT, WIND, WATER ANDBIOMASS
ELECTRICAL ENERGY IS USED TO POWER MACHINES. WE CAN TRANSFORM IT INTO LIGHTTT, SOUND, HEAT AND MOVEMENT.
A LOT OF OUR ELECTRICITY IS STILL PRODUCE BY BURNING FOSSIL FUELS
.
THERMAL ENERGY
THE THERMAL ENERGY FLOWS FROM A WARM SUBSTANCE TO A COOLER SUBSTANCE
.
A CHANGE IN THE THERMAL ENERGY OF A SUBSTANCE CAN ALSO MAKE THE SUBSTANCE CHANGE STATE.
THE SUN IS THE MAIN SOURCE OF HEAT ON EARTH.
THESE FUELS COME FROM UNDER THE GROUND AND INCLUDE COAL, OIL AND GAS.
.
OTHER SOURCES INCLUDE FOSSIL FUELS, WHICH WE USE TO WARM OUR HOUSES AND COOK OUR FOOD.
SOUND ENERGY
SOUND CAN TRAVEL VERY QUICKLY, BUT NOTAS FAST AS LIGHT.
➖⬜➕
SOUND CAN TRAVEL THROUGH GASES, LIQUIDS AND SOLIDS, EVEN IF THEY ARE OPAQUE.
WE PERCEIVE LARGE VIBRATIONS AS LOUD SOUNDS AND SMALL VIBRATIONS AS SOFT SOUNDS
↔
SOUND CAN´T TRAVEL THROUGH A VACUUM BECAUSE IN A VACUUM THERE ARE NO PARTICLES TO VIBRATE.
:red_cross:
SOUND IS A VIBRATION AND CAN TRAVEL IN ANY DIRECTION FROM THE SOURCE.
THE VIBRATIONS MOVE THROUGH THE AIR.
