Static Electricity - the accumulation of charges - i.e.
protons, electrons. For example, when you rub your feet along the
carpet you are rubbing off the negatively charged electrons and gaining a
fixed positive charge on your body. When you come into contact with
another object that is grounded, the electricity goes from where there is
a lot (ground) to where there is a lack (you) and you get an electric shock.
Kinetic Electricity - the motion of a collection of charges -
i.e. protons, electron
Circuit - the closed loop traveling path of electrons
Voltage - electrical pressure (electromotive force). Think of
it as the 'push' or 'kick 'to the electrons flowing in the circuit.
Conductor - a material through which energy (i.e. heat, electricity)
can flow easily
Insulator -a material through which the flow of energy (i.e.
heat, electricity) is restricted.
Ground - an electrical connection to the electrically neutral
Permanent Magnet - either a metal extracted from the earth already
magnetized, such as magnetite, or a metal that becomes magnetic in the
presence of a strong magnetic field.
Electromagnet - a core of metal which becomes magnetic when there
is a wire with current wrapped about it. The stronger the current and the
more loops of the wire, the stronger the magnet becomes.
Induction - a moving magnetic field near a loop of wire can
induce an electric current in the wire. When a current moves in a loop
about a metal core, a magnet is induced.
Piezoelectric - a material in which voltage is induced when under
stress, such as when it is bent out of shape. The strip also changes its
when voltage is applied to it.
