Newton's firstlawof motion - sometimes referred to as thelaw of inertia. An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
Avoltaic cellis an electrochemicalcellthat uses a chemical reaction to produce electrical energy. The important parts of avoltaic cell: The anode is an electrode where oxidation occurs. The cathode is an electrode where reduction occurs.
Electrolyte is a solution containing ions that can conduct.
Anelectrodeis an electrical conductor used to make contact with a nonmetallic part of a circuit (e.g. a semiconductor, an electrolyte or a vacuum).
