The Earth is a magnet. The Law of Conservation of Energy Energy cannot be created or destroyed . E= m x C 2 Matter can be converted into energy . Energy given off when there is a change in the nucleus of atoms. Electrical Energy the force of moving electrons. Electrical Energy (electricity) energy resulting from the force between two objects having different voltages. Voltage The potential energy of the electrons in a circuit. Current The amount of electrons flowing in a circuit. Resistance How much the circuit impedes the flow of electrons. Electricity filament Electricity - electrons moving through a metal wire. D.C . Direct Current A.C. Alternating Current Atomic Absorption Atomic Emission Magic is technology that is not understood. Flame test A television is an Electron Gun 9V + -with dc voltage Generating an Electric Field-+ 9V + -dc voltage Generating an Electric Field e e-1-1-+ e e-1-1 e e-1-1 e e-1-1 e e-1-1 e e-1-1 e e-1-1 e e-1-1 Static electricity Static Electricity when a material has an excess or a lack of electrons. A Capacitor holds a charge on its plates. Electrical Energy Induction Thermocouple (copper & nickel or copper & iron) Circuits Series Parallel Lamp 1 Lamp 2 Switch 1 Switch 2 Short circuit Foil (glued onto bottom half of stick) Wire coil (covered with glue) Wire ends ( stripped ) Coil tube Wood shtick El Motor ‘ Foil (through bottom of holes) Magnets Motor Box Circuit Board Integrated circuits On a hot day, Jenny walked home with a bag of chocolate chips. When she arrived the chocolate chips had melted in the bag. Why did they melt? Heat transferred from the chocolate chips to the bag. Heat evaporated from the bag to the chocolate chips. Heat transferred from the environment to the chocolate chips. Heat condensed from her hand to the chocolate chips. Energy appears in many forms. What form of energy is lightning? electrical energy mechanical energy magnetic energy sound energy A glass of water kept at room temperature long enough will become empty because water molecules slowly leak through the walls of the glass. water molecules move into the air as gas molecules. water left in a glass starts to boil and becomes a gas....
