energy
| Question | Answer |
|---|---|
| the ability to do work or cause change | energy |
| work is the transfer of_______ | energy |
| energy is measured in _________ | joules |
| 2 general kinds of energy | potential kinetic |
| transfer of energy - the energy of motion/kinetos | kinetic energy |
| wheather the energy is kinetic or potential deponds on tis _________ and ________ | mass velocity |
| kinetic energy __________ as mass__________ | increases |
| has the potential 2 do work | potential energy |
| 2 types of potential energy | elastic potential energy gravitational potential energy |
| potential energy associated withobjects that can be stretched or compressed | elastic potential energy |
| potential energy in objects that must be lifted rolled pushed etc.objects that can fall also have this | gravitational potential energy |
| some major forms off energy are:(6) | mechanical thermal, chemical, electrical, electromagnetic, nucleor |
| all atoms and molecules have this- when particles move they produce heat- the faster the particles the more heat they produce | thermal energy |
| energy in chemical bonds (atoms that are chemically connected such as H2O foods have this -you burn caleries, you produce this - when you burn anything youre breaking down chemical bonds | chemical energy |
| produced by moving changes of electricity | electrical energy |
| 2 kinds of electrical energy | static electricity |
| where is electrical energy found in | batteries or power lines |
| energy that travels in waves - found in microwaves , radiation (uv,ir,etc.) | electromagnetic energy |
| potentiaal energy stored n the nucleous of an atom | nucleous energy |
| type of nuclear energy released whenatoms are split | fission |
| type of nuclear energy released when atoms are joined together | fussion |
| change | convert |
| change or transform | conversion |
| any formof energy can B converted nany other form | energy conversion |
| ________________ is thermal energy | body temp. |
| chemical energy is converted into _____________ your brain uses to thnk | electrical energy |
