|
|
||||
|---|---|---|---|---|---|
| energy | the ability to cause changes in matter
🗑
|
||||
| Law of Conservation of Energy | law that states that the total amount of energy in a system is always the same....energy can't be created or destroyed
🗑
|
||||
| kinetic energy | the energy of motion....the ability to extract a force on matter that comes into contact with it
🗑
|
||||
| potential energy | stored energy....energy that is due to the position or condition of an object
🗑
|
||||
| thermal energy | heat energy...kinetic energy of the moving particles of a substance or object
🗑
|
||||
| heat | thermal energy that is transferred
🗑
|
||||
| conduction | energy is passed on due to the collision of particles
🗑
|
||||
| convection | when a liquid or gas is heated up, it expands, and its density decreases....hot materials rise over cool ones
🗑
|
||||
| radiation | transfer of energy in waves...thermal is a type
🗑
|
||||
| Iron, Cobalt, and Nickel | substances in which magnetism can occur
🗑
|
||||
| domain | a small group of atoms
🗑
|
||||
| magnet | all of the domains of a substance align in the same direction
🗑
|
||||
| electricity | the interaction of electric charges...the moving of electrons
🗑
|
||||
| electric energy | the movement of energy from one place to another...the moving of electrons
🗑
|
||||
| electric circuits | enable electric currents to travel....must be continuous with no gaps
🗑
|
||||
| static electricity | charges that are present, but don't flow form one place to another
🗑
|
||||
| current electricity | the flow of electric charge
🗑
|
||||
| series circuit | the wires all go in one direction hopping from one resistor to another
🗑
|
||||
| parallel circuit | the electrons have different paths of wires and don't have to go in one set order
🗑
|
||||
| electromagnet | a magnet ran by electricity that can be turned on and off
🗑
|
||||
| chemical energy | a form of potential energy stored in reactants
🗑
|
||||
| fission | atoms fall apart....some energy is given off (power plants and bombs)
🗑
|
||||
| fusion | putting atoms together....lots of energy is given off (Sun and big bombs)
🗑
|
||||
| boiling point of water | 212 f or 100 c
🗑
|
||||
| melting point of water | 32 f or 0 c
🗑
