the ability to cause an object to 1. move, change, or work 2. trade-off something that you do not want, but have to accept in order to have something that you want (disadvantage) 3. variable a changing factor; in an experiment the variable is what is studied 4. transfer when MOVES from place to another 5. transformation when CHANGES from one type to another
6. gravitational potential a type of potential due to an object s position above the earth 7. potential stored that has not yet been used 8. kinetic in motion 9. thermal that is transferred from a warm object to a cool object
10. friction a force that exists at the boundary between any two objects that are in contact with each other 11. transferred MOVED from one place to another 12. transformed CHANGED from one type to another 13. heat the movement of thermal from hot to cold 14. temperature a measure of the average per molecule of a substance; a measure of thermal
15. scientific law a phenomenon of nature that has been proven to occur repeatedly, whenever certain conditions exist 16. Law of Conservation of Energy the scientific law that states that can be transferred or transformed, but cannot be lost or destroyed 17. efficiency the ratio of useful released to total absorbed by a process 18. conservation 19. chemical to reduce or save the total transformed a type of potential where the is stored in the
20. elastic Energy Vocabulary bonds of atoms (ex. in foods or fossil fuels) potential that is stored by stretching or compressing 21. electrical 22. nuclear (current) movement of and charge from one place to another (static) stored by the build-up of charge potential that is stored in the nucleus of an atom (ex. stored in the center of the sun) 23. light kinetic that is transferred by the rapid movement of electromagnetic fields
24. sound kinetic transferred by the vibration of an object 25. conduction the flow of heat, electricity or sound through a material 26. conductor a material or object that allows to move through it 27. control (sample/group) an experimental group in which everything is the same as in the rest of the experiment; used to make a comparison 28. insulation a material that is used to slow down or prevent the flow of through it 29. insulator a material that is resistant to the flow of
30. calorie a measure of heat ; amount of needed to raise one gram of water one degree Celsius 31. calorimeter a device that measures the amount of chemical potential in a material 32. renewable resource 33. non-renewable resource a source of material that can be easily produced again and again in nature (ex. wood, solar & hydroelectric power & crops) materials that cannot be easily or quickly replaced by natural systems (ex. fossil fuels) 34. biomass material from living things, such as plants and animals, that is used as a source of fuel 35. fossil fuels a fuel produced by living plant materials that have been buried
and changed by heat and pressure under layers within earth over millions of years (ex. natural gas, petroleum, coal) 36. hydroelectric power generated by moving water which turns a turbine, which generates electricity 37. power plant a facility that transforms into electricity and distributes it to the surrounding area 38. turbine a machine that uses kinetic from moving wind, water, steam or gas to generate mechanical and run a generator 39. generator a machine that makes electricity by transforming the rotating of a turbine into electricity
40. wind from the wind that causes a turbine to turn in order to generate electricity 41. solar that comes from the sun 42. absorb to take in or capture light and transform it into heat 43. transmit to allow to pass through 44. reflect to bounce light off of an object
