| energy | the ability to cause change |
| potential energy | stored energy |
| kinetic energy | motion energy |
| these two things effect kinetic energy | mass and speed |
| these two things effect potential energy | position and condition |
| when a ball is dropped from a high height the potential energy is | at its greatest at the very top before released |
| when a ball is dropped from a high height its kinetic energy is greatest | the instant before it hits the ground |
| The Law of Conservation of Energy | Energy can't be created nor destroyed only changed |
| Do have the same amount of energy in our universe as the beginning of time | we have always had the same amount of energy and always will |
| this is when one energy is changed into another energy | energy transformation |
| the amount of kinetic energy of particles in a warm material is | higher than the KE of particles in a cooler material |
| does thermal energy go from warm to cold or cold to warm | warm to cold |
| Conduction | this is the bumping of particles to increase the KE |
| Convection | this is the moving of particles from one place to another depending on the temperature |
| Radiation | this process uses waves and can be found in microwaves |
| These are the 3 ways of transferring thermal energy | radiation convection and conduction |
| 0 degrees Celcius | This is the freezing point in degrees celcius |
| 100 degrees Celcius | this is the boiling point in degrees celcius |
| 32 degrees Fahrenheit | this is the freezing point in degrees fahrenheit |
| 212 degrees Fahrenheit | this is the boiling point in degrees fahrenheit |
| 0 Kelvin | This number represents absolute zero |
| Absolute Zero | This is the coldest anything can be |
| Conductors | these allow thermal energy to be transferred nicely |
| Insulators | These allow thermal energy to be transferred poorly |
| Metals | These would be considered good conductors |
| A pizza box | This would be considered an insulator |
| Chemical energy | Energy that is stored within chemical bonds |
| Exothermic Reactions | Reactions where energy is released or exits |
| Endothermic Reactions | Reactions where energy is absorbed or taken in |
| Fat | This is where our body stores most of its energy |
| Food | This is where our body gets most of its energy |
