This document defines and describes various forms of energy including chemical energy, electrical energy, gravitational potential energy, kinetic energy, light, sound, thermal energy, and nuclear energy. It also discusses renewable and nonrenewable resources. Key energy terms are defined such as fossil fuels, global warming, hydroelectricity, electromagnetic radiation, and the differences between nuclear fission and fusion.
Energy conversions 2
- 2. CHEMICAL ENERGY ENERGY STORED IN THE BONDS THAT HOLD MOLECULES TOGETHER.
- 3. ELECTRICAL CURRENT ENERGY THAT RESULTS FROM THE MOVEMENT OF CHARGED PARTICLES.
- 4. ENERGY THE ABILITY TO CAUSE CHANGES, EXERT FORCES OR DO WORK. (IN OTHER WORDS, ENERGY IS THE ABILITY TO MAKE THINGS HAPPEN!)
- 5. ENERGY CAN EXIST IN MANY FORMS. IT CAN BE STORED OR EXPRESSED ACTIVELY. ENERGY CAN BE CONVERTED TO ANOTHER FORM, BUT CAN NEVER BE CREATED OR DESTROYED.
- 6. FOSSIL FUEL A FUEL FORMED DEEP IN EARTH’S CRUST FROM THE REMAINS OF PLANTS AND ANIMALS. FOSSIL FUELS INCLUDE COAL, OIL, AND NATURAL GAS.
- 7. GLOBAL WARMING A GRADUAL RISE IN EARTH’S AVERAGE TEMPERATURE.
- 8. GRAVITATIONAL POTENTIAL ENERGY STORED ENERGY THAT IS DUE TO AN OBJECT’S POSITION. THE HIGHER AN OBJECT IS, THE GREATER ITS GRAVITATIONAL POTENTIALENERGY.
- 9. HYDROELECTRICITY ELECTRICAL CURRENT PRODUCED BY WATER FLOWING THROUGH A TURBINE.
- 10. KINETIC ENERGY ENERGY OF MOTION. THE FASTER AN OBJECT MOVES, THE GREATER ITS KINETIC ENERGY. KINETIC ENERGY ALSO INCLUDES SOUND AND THERMAL ENERGY:
- 11. SOUND –ENERGY OF VIBRATING MATERIALS OR AIR MOLECULES.
- 12. THERMAL ENERGY ENERGY THAT COMES FROM THE MOVEMENT OF TINY PARTICLES. AS AN OBJECT HEATS UP ITS PARTICLES MOVE FASTER, INCREASING THERMAL ENERGY.
- 13. LIGHT A FORM OF ELECTROMAGNETIC RADIATIONTHAT IS VISIBLE TO THE EYE
- 14. ELECTROMAGNETIC RADIATION OTHER FORMS OF ELECTROMAGNETIC RADIATION INCLUDE GAMMA RAYS, X-RAYS, ULTRAVIOLET LIGHT, INFRARED RADIATION, AND RADIO WAVES.
- 15. NONRENEWABLE RESOURCE A NATURAL RESOURCE THAT CANNOT BE REPLACED REASONABLY SOON.
- 16. NUCLEAR ENERGY ENERGY RELEASED BY CHANGES TO THE NUCLEI OF ATOMS.
- 17. NUCLEAR FISSION IN NUCLEAR FISSION, ATOMS ARE SPLIT APART. IT IS USED IN POWER PLANTS AND WEAPONS.
- 18. NUCLEAR FUSION IN NUCLEAR FUSION, ATOMS ARE JOINED TOGETHER. THIS OCCURS DEEP INSIDE THE SUN. THERE IS HOPE THAT WE WILL SOON BE ABLE TO HARNESS THIS TYPE OF ENERGY, ESSENTIALLY SOLVING THE ENERGY SUPPLY PROBLEM.
- 19. RENEWABLE RESOURCE A NATURAL RESOURCE THAT CAN BE REPLACED IN A REASONABLE AMOUNT OF TIME.
- 20. RENEWABLE RESOURCES WIND POWER, SOLAR POWER, HYDROELECTRICITY, AND ETHANOL ARE RENEWABLE RESOURCES.
- 21. SOUND SOUND IS ENERGY THAT TRAVELS AS A RESULT OF VIBRATION. IT CAN BE CHARACTERIZED BY FREQUENCY, PITCH, AND LOUDNESS, WHICH IS MEASURED IN DECIBELS.
- 22. SOURCES CLIPART FROM BING ONLINE AND COMMONSHARES
- 23. THERMAL ENERGY THERMAL ENERGY IS THE ENERGY A SUBSTANCE OR SYSTEM HAS RELATED TO ITS TEMPERATURE, I.E., THE ENERGY OF MOVING OR VIBRATING MOLECULES. THERMAL ENERGY IS NOT THE SAME AS HEAT. HEAT IS ENERGY TRANSFERRED BETWEEN SUBSTANCES OR SYSTEMS DUE TO A TEMPERATURE DIFFERENCE BETWEEN THEM.
