A | B |
Energy | the ability to cause changes in matter |
Law of conservation of energy | states that the total amount of energy in a system is always the same |
Energy can not | be created nor destroyed |
Moving objects | have kinetic energy |
Kinetic Energy | has the ability to exert force on matter that comes in contact with it |
The faster an object is moving- | the more kenetic energy it has |
Potential Energy | energy that is due to the position or condition of an object |
Thermal Energy | the kinetic energy of moving particles or a substance |
Heat | thermal energy that is transfered |
Conduction | heat resulting from collision of particles |
Convection | thermal energy that is transfered from fluids, liquids, and gases |
Radiation | the transfer of thermal energy in waves |
Magnets | have all of the domains of a substance are alinged in the same direction |
Positives | repel |
Opposites | attract |
Electricity | electrons that have a negative charge-the interection of electric charges |
Electric Energy | movement of energy frm one place to another |
Circuit | an electric energy source that is connected |
Electro magnet | a magnet that runs by electricity that can be turned on and off |
Chemical Energy | the form of potential energy stored in reactants |
Nuclear Energy | bonds holding the protons and the neutrons of an atom's nucleus together |
Fission | occurs when a nuclues breaks into two parts |
